When Unicode web pages containing Hebrew/Yiddish Diacritic marks are displayed using the BiDi version of mozilla (ftp://ftp.software.ibm.com/ps/products/warpzilla/bidi-win32-rel-11-13.zip) they appear BESIDE the character that they should appear BENEATH. When the font is altered in preferences (and force font) to Lucidia Sans Unicode, then they appear correctly. Fonts that work in IE5 but not Mozilla include: Tahoma (tested) Frankruehl (reported by 3rd party) Some explanation as to why some fonts work and others do not would be useful, but ultimately it would be prefferred if they all could work.
Created attachment 19429 [details] The Font Frankruehl displayed correctly rendering this page in IE, wrong in Bidi-Mozilla
I got these comments from Mark David, from Yiddish Information Processing (uyip.org). Oh, I see. Someone got this to work with the Lucida font, but not the normal Windows Hebrew fonts. The Lucida font is broken for Hebrew. My Microsoft sources say this is known, but cannot be changed for compatibility with existing applications. This font has been around since Windows NT 3.51, around 1994. In fact, Internet Explorer with Hebrew extensions has not been fixed to compensate for Lucida's problems, and only works for the standard Hebrew fonts, and displays nikud wrong ONLY with Lucida. It's very nice to have "special" code that makes it display Hebrew correctly, but the display code should also handle correctly constructed fonts, in particular the standard Hebrew fonts supplied with Hebrew-enabled Windows 98/NT/2000 and with Hebrew extensions for Internet Explorer 5. E.g., Arial, Times-Roman, Tahoma, Frankruehl, et al. Sure enough I could reproduce this with a plain text page http://uyip.org/rotshd-cp1255.txt I simply had to explicitly say the encoding is Hebrew Windows Code Page 1255 under View -> Character Coding.
Reassign to mkaply, cc erik.
Arthur is this still a problem in the latest nightlies?
I will check ASAP, however we just relocated our office and so this may take me a few days.
Arthur any luck reproducing?
new bidi code should be checked in by mkaply soon pending review of his changes. Look for the bug out there.
Tested with a WinNT 4.0 compiled copy of the latest (9/Jan/01) BiDI source code. Still does exactly the same thing. This is not good ... No-one has yet offered an explanation as to why this is happening either... I will upload a binary copy of the WinNT build some time over the weekend and post a URL when available. The source code is from ftp://ftp.software.ibm.com/ps/products/warpzilla
Marking NEW as per comments.
URL of binary for Win NT is: http://march-hare.com/downloads/bidimoz.zip It is a debug build weighing in at 48Mb.
To reproduce with teh text file, you need to Choose the character coding (View -> Character Coding -> More -> Middle Eastern ) Hebrew (Windows 1255). http://uyip.org/rotshd-cp1255.txt And set the font (Preferences, Font, Hebrew) to Tahoma. To reproduce with the Unicode HTML page (See attachment), set the character set to Unicode UTF-8 and set the preferences font for Unicode to Tahoma. So I guess this means that it is not Unicode specific, since it also reproduces with CP1255 ?
After some e-mails from Lina I thought I should clarify: I am using standard Windows NT 4.0 + SP4. I've never heard of "Hebrew Enabled" versions, and do not need "Hebrew Enabled" for these same pages to work fine in IE5 (even with Tahoma). I have heard of the Microsoft localised Hebrew Windows NT, but not Hebrew Enabled.... I will now attach bitmaps of Lina's page in both bidi Mozilla, and ie5, on the same machine, same font etc etc. (http://www.qsm.co.il/Hebrew/HebrewTest/test5.htm)
Created attachment 23252 [details] http://www.qsm.co.il/Hebrew/HebrewTest/test5.htm in Mozilla font Tahoma (from Office 2000)
Created attachment 23253 [details] http://www.qsm.co.il/Hebrew/HebrewTest/test5.htm in IE5.5 using Font Tahoma (from Office 2000)
After investigating a number of different fonts from different sources, I have come to the conclusion that Hebrew nikud is broken in all Microsoft Hebrew fonts: Lucida Sans Unicode is broken in one way, and other fonts such as Tahoma are broken in another way. Microsoft's own programs with Hebrew support (whether Bidi enabled NT or IE5) are capable of displaying text in Hebrew script with nikud correctly, but the standard text-output APIs are not. Finding a workaround for this problem is not trivial: we will probably have to detect text with nikud and send it to special output methods, while also sniffing the current font to work out in what way it is broken and how to compensate (or whether it is a compliant third party font).

Switching QA contact to email@example.com.
Copied from n.p.m.i18n: In spite of their otherwise good BIDI support, Mozilla 0.9.1 and 0.9.2 as well as the nightly build as of yesterday fail to display Hebrew diacritics in correct positions above letters if the CSS property TEXT-ALIGN is set to the value JUSTIFY, whether internally or externally, for an inline element containing the combination of Hebrew letters and diacritics. It took me a while to pin down this as the environment of the buggy display. ---------------------------------------------------------------- Tsuguya Sasaki, PhD E-mail: firstname.lastname@example.org WWW: http://www2.gol.com/users/tsuguya/ ----------------------------------------------------------------
I'd attatch a sample of what Tsuguya is talking about, but Bugzilla currently wont let me. You can see it at http://mail.hlmm.com.au/diacritics.html If you have problems with this URL - contact me direct. The original example URL (as above) uses a stylesheet: http://www2.gol.com/users/tsuguya/ts.css This uses justify for the <body> tag - so it looks like this is the bug.
Mass-move all BiDi Hebrew and Arabic qa to me, email@example.com. Thank you Gilad for your service to this component, and best of luck to you in the future. Sholom.
Confirming this is still present in 0.9.5 for Linux. The user reports: diacritics are placed after, not with, corresponding letters. My font setting is for Hebrew misc-fixed-iso8859-8; for Unicode (all styles) misc-fixed-iso- 10646-1. In fact, I am certainly not seeing my Yiddish text in the latter font, even though Mozilla claims that it is using Unicode encoding. I may be seeing it in the former font, but I'm not sure. The URL I am looking at is http://www.cs.uky.edu/~raphael/bavebter/numer.1.3/sholem.redak.utf.html
*** Bug 127050 has been marked as a duplicate of this bug. ***
This may have something to do with OpenType Layout Tables which allow to display spacing diacritics as if they were properly aligned nonspacing diacritics. But this is just a guess. You can get some info about Visual OpenType at http://www.microsoft.com/typography/developers/volt/ and http://communities.msn.com/MicrosoftVOLTuserscommunity/ Gyula
It has nothing to do with OpenType Layout Tables.
Mozilla 0.9.9: Works under Windows, fails under Linux.
The bug is still there in Mozilla 1.0 Release Candidate 1. I am using Windows 98 original edition.

No improvement in Version 1.0 RC2.
Created attachment 89520 [details] Looks fine in Build#2002053012 The diacritics seems to render almost perfect on my build. Only problem I can see is with the 'Holam' (?) sign, which is followed by an unnecessary space (see second word, 'Ovadia', in http://www.qsm.co.il/Hebrew/HebrewTest/test5.htm ). Of course this might be fixed in lately builds, I'm not sure.
Under Linux this is still a problem? Is there a bug for Linux or should I change this bug to All OS?
re comment 32: I think the Holam problem is a bug in specific fonts. I see the extra space after the Holam in Arial, Arial Unicode MS and Tahoma, not only in Mozilla but also in Wordpad and IE. In other fonts, the extra space disappears. re comment 33: we have bug 81367 for the corresponding problem on Unix systems, and bug 144157 for a more limited problem with diacritics on Mac.
as of build 2002061603, the page still looks bad on osx,
Where can I get the build compiled by Sagie Maoz and when will his corrections be added to the official build?
You must be confusing me with somebody else, I don't do patches :)
There is no available BiDi build yet that properly displays Yiddish.
AbiWord suffers from a similar bug: http://bugzilla.abisource.com/show_bug.cgi?id=3768 Could the two teams join forces? More bugs with screenshots that show the same wrong alignment: Bug 123218 and Bug 144157

There seems to be a general problem with the diacritcs rendering after the base character; I'm seeing the problem on Win98 with mozilla 1.3 except I'm not using Hebrew; simply trying to combine a ^ with a z for example.
in addition there is something funny: if I write: Hachodesch (החודש) hebrew is wrong direction. it is right direction in internetexplorer. if I write: Hachodesch (<bdo dir="rtl">החודש</bdo>) it does not change it I write: Hachodesch (<bdo dir="ltr">החודש</bdo>) it displays correctly. But wrong with internetexplorer. this sample is from www.synagogenverein.at/bethaus.asp this is a terrible thing :'(. not even unicodes but also "<bdo dir" tags are misinterpreted! please fix. johannes
Comment 44 is completely unrelated to this bug. Can you please file a separate report?
Not only for Yiddish, same for hebrew: http://www.mechon-mamre.org/i/t/t0101.htm Please fix so we can stop use IE.
Sometimes when the diacritics display incorrectly in the way described here, the line of text goes beyond the margin, but sometimes it does not. Is this behavior just a side-effect of this bug, or does it need its own bug? Such a bug has been filed as bug 209468.
*** Bug 210122 has been marked as a duplicate of this bug. ***
See also bug 212808 which is partly a duplicate of this one. The behaviour of a page of fully cantillated biblical Hebrew, http://www.mechon-mamre.org/c/ct/c0101.htm (in Mozilla 1.4 on Windows 2000), with font Ezra SIL (OpenType, designed specially for biblical Hebrew, from www.sil.org) set as the default depends on the version of Uniscribe installed, but even with the latest version of Uniscribe set for release with Office 11 there is a diacritic placement problem, not found with IE6. Actually this is not really this bug at all as originally reported. It looks to me as if this bug started with incorrect behaviour of some pre-OpenType Microsoft etc fonts which would be the same in IE as in Mozilla. The problem I am reporting has similar symptoms but is Mozilla specific. It seems to be a matter of Mozilla failing to use Uniscribe and OpenType tables properly. Should I open a new bug or continue this as bug 212808? But comment 46 here may be related to what I am reporting, although http://www.mechon-mamre.org/i/t/t0101.htm, on the same site as my problem page, has no cantillation marks and is encoded in CP1255 rather than UTF-8.

Is anybody working on this bug now? I'm trying to look into it. Is use of Pango to display text in mozilla out of question? (Pango is a library used by GNOME for displaying text, it seems to handle Hebrew diacritics successfully.)
As for using Pango on Linux, see bug 215219. My patch there works well for justified as well as unjustified text. However, I'm not dealing with Hebrew and Arabic in the patch because I'm not sure what Mozilla's internal Hebrew/Arabic routine does. On Windows, we have to use Uniscribe APIs instead of standard Windows text drawing APIs to render justified text correctly (see bug 218887) . BTW, is there any freely available opentype font for Hebrew supporting Hebrew diacritic marks?
Re comment 54, see Ezra SIL from http://www.sil.org/computing/fonts/silhebruni/. See also http://www.sbl-site.org/Resources/Resources_BiblicalFonts.aspx; the long promised new Unicode Hebrew font will be very good, from what I have seen of the beta, but unfortunately it is has not yet been released. There is also an initiative for using the SIL Graphite rendering system within Mozilla, see http://sila.mozdev.org/. This might be useful for rendering Hebrew and Arabic. Unfortunately SIL's Hebrew font does not work with SIL's rendering system, because it does not include a Graphite table.
Thanks for the info. about SIL opentype fonts for Hebrew. With them installed, Mozilla on Win 2k works well for _unjustified_ Hebrew with diacritics (vowel marks). That's expected because ExTextOutW (Win32 API) used by Mozilla can take care of complex script rendering given a 'enough' context on Win2k/XP (and Hebrew/Arabic Windows 9x/ME for Hebrew/Arabic and Thai Win 9x/ME for Thai) However, it doesn't work for 'justified' text. For that, we have to use Uniscribe (bug 218887). Now, I'll see how Pango works on Linux. As for SILA, I'm aware of that, but as you pointed out, without Graphite fonts for Biblical Hebrew, it's not useful.
The URL returns 404, so I replaced it with the one from Bug 144157. It should be sufficient for testing this bug. Prog.
Dov Grobgeld has submitted a patch to pango to use GPOS and GSUB tables in Hebrew fonts. See http://article.gmane.org/gmane.linux.region.israel.ivrix.discuss/921 and http://bugzilla.gnome.org/show_bug.cgi?id=150785.
blizzard recently added nsFontMetricsPango to mozilla trunk. (the relevant bug is bug 214715, but he just did it off-line) To test it, you need to install pango 1.5 (plus the patch for GPOS/GSUB support in Hebrew mentioned ) and build mozilla with 'enable-pango'.
This is my first bugzilla comment in Mozilla, so please excuse me if I'm not too familiar with how the rendering works. From the discussion above, I don't understand if you are going all the way to using pango. If you are the rest of this comment is irrelevant, as you will receive the below functionality from pango. If not you may want to consider to copy my heuristics that is encoded in the Hebrew module. This heuristics does a reasonable job of nikkud placement for fonts without GPOS and GSUB tables by simple rules such as "PATAH should be centered below the character", "SHIN DOT should be right aligned", etc. The result is imho really good enough.

This result may be good enough for basic pointed Hebrew. But it will not be good enough for fully pointed and accented Hebrew as use e.g. in the Bible text, which is rendered successfully by pango with Dov's patch (see his samples). There is a significant demand for reading the Hebrew Bible online, and several sites at which it is available e.g. http://mechon-mamre.org/c/ct/c0.htm and http://users.ntplx.net/~kimball/Tanach/Tanach.xml. These sites already work well with IE, and in fact with Mozilla 1.7 on Windows XP. I hope Mozilla won't be satisfied long term with a partial solution but will implement full pango rendering of Hebrew - and I hope Dov's patch will make it into the pango trunk.
FYI, I got permission to and applied the (modified) patch to the main pango trunk yesterday. Regarding heuristics, it is true that the current heuristics that is in the pango Hebrew renderer does not handle fully pointed and accented Hebrew. But I am convinced that it may be changed to do that. The rendering heuristics has access to complete bounding box information as well as the coding of the glyphs. That is enough to do make sure that the various marks do not collide. Don't take the current implementation in pango (which ignores accents) as an indication that is not possible! The problem with using opentype tables is pushed to the font designer who has to create tables for several thousand potential combinations. One idea I have is to use e.g. the online tenach to automatically generate all possible combinations, and then use some automatic layout routine (e.g. involving distance transforms) to generate all the different GPOS combinations... But now I am getting carried away. Thus my question remains. Is Mozilla moving over to using pango?

Sounds good for use with a font which doesn't have all the GPOS etc information set up. But when you have a font like SBL Hebrew which has been designed carefully so that all (or nearly all) of those several thousand combinations are supported, surely it is better to use that information rather than try to do better with heuristics.
Blizzard - this question is for you. > Thus my question remains. Is Mozilla moving over to using pango?
*** Bug 257756 has been marked as a duplicate of this bug. ***
I don't think there's any official mozilla.org policy on this. I will say, however, that I've added support for pango in Mozilla. I think we (Red Hat) intends to ship this in some upcoming version of Fedora. It does do a better job with a lot of scripts including arabic and hebrew. It's worth checking out.
I have just compiled firefox cvs with --enable-pango on debian unstable, I can see diacritic in the correct palce using culmus fonts. (http://benyehuda.org/bialik/bia001.html) but: 1. when using text-align justify the text gets all mixed up: (http://www.mechon-mamre.org/c/ct/c0101.htm) 2. printing hebrew is reversed.

Hi, I'm wondering when this will finally be fixed! For me, it's quite a serious problem, not having the vowels and cantilation marks placed correctly. I have the Ezra SIL SR font installed and am trying to look at the Bible with vowels and cantillation marks at http://www.mechon-mamre.org/c/ct/c0101.htm . Some observations: Aside from mozilla, the following applications seem to have the same problems: epiphany, openoffice (both in linux and windows), scribus (and IIRC mozilla/firefox in windows as well!) The following apps do NOT have the problem: MS IE, MS WORD, and Konqueror (I run it in gnome). ^^^^^^^^^ So another linux app has managed to fix this! Could we please fix it in Mozilla soon? Please? Thanks, HCY.
(In reply to comment #70) > ... the Bible with vowels > and cantillation marks at http://www.mechon-mamre.org/c/ct/c0101.htm . > > Some observations: > > Aside from mozilla, the following applications seem to have the same problems: > epiphany, openoffice (both in linux and windows), scribus (and IIRC > mozilla/firefox in windows as well!) I can confirm that this problem is still found with this page in Mozilla 1.7 on Windows, and this continues when I edit the page in Composer and change the font to SBL Hebrew. But the problem may be just with this page. The pages http://www.cvkimball.com/Tanach/Genesis.DH.xml and http://www.anastesontai.com/b-cantilee/en-cant.asp display the same text correctly, with SBL Hebrew. Is there a subtle setting in the stylesheets causing the difference?
I get the same problems with those sites as well. HCY.
I'm fairly sure I've said this before, but if so I'll say it again. On Windows the diacritics and cantillation marks are displayed correctly (via Uniscribe), except where there is "align=justify" or the equivalent in CSS. On Linux and other platforms, the problem exists with or without justification. The Pango support which is currently in development (bug 214715, marked as blocking this one) should bring Linux at least into line with Windows. The other blocker, bug 218887 should cover the justify issue on Windows. I am adding bug 215219 as blocker, which is the Linux equivalent of bug 218887.
(In reply to comment #73) > The Pango support which is currently in development (bug 214715, marked as > blocking this one) should bring Linux at least into line with Windows. It turns out that non-justified text in Linux builds with Pango enabled is already at least on a par with Windows. See attachment 176897 [details] in bug 285007.

(In reply to comment #73) > On Windows the diacritics and cantillation marks are displayed correctly (via > Uniscribe), except where there is "align=justify" or the equivalent in CSS. > > On Linux and other platforms, the problem exists with or without justification. I have been working on fixing these issues in Firefox - see my web page http://blacksapphire.com/firefox-rtl/ for my latest work on these bugs. For rendering Hebrew with vowels+cantillation marks, there are FIVE bugs present as of Firefox-1.0.4: 1. (GTK-based Unix, including Linux). As previously described, the default renderer does not render Hebrew properly, while Pango does. Since some languages render better in Pango and some in Mozilla default, it would be nice to have it automatically select between the two for each language. 2. (All platforms). In layout/html/base/src/nsTextFrame.cpp, PaintTextSlowly is called when "align=justify" is used. PaintTextSlowly does not render Hebrew properly even with pango enabled. I fixed it by making it always use PaintUnicodeText/PaintAsciiText when bidi is enabled. See the patch on my site. 3. (All platforms). Justified text (with "align=justify") looks very strange, because it treats whole sentences as a single word. I fixed this in layout/base/src/nsBidiPresUtils.cpp by changing CalculateCharType so it starts a new text run when it sees a white space. The Mozilla people might have a better way to fix this. 4. (All platforms). The Hebrew Biblical texts have the occasional single letter that is larger or smaller than usual (e.g. Genesis 1:1 and Genesis 2:4). When "align=justify" is used, along with HTML to give a different-sized character (as in the Mechon-Mamre texts), the odd character ends up as a different "run". In some situations (certain font sizes on Windows), the justify algorithm puts a gap in between. Justify really should only add extra space where there is *actual whitespace*. I haven't fixed this yet. 5. (All platforms). Printing is all wrong with one or two words per line and big gaps. I have not tracked this one down.
Stephen, make sure your work and smontagu's aren't conflicting; he's working on related issues in bug 297074.

I've just upgraded to Firefox 1.5 (Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20051202 Fedora/1.5-0.fc4 Firefox/1.5) on Linux (Red Hat Fedora Core 2). Previously I'd been using Mozilla 1.7.3, and, by using a Mozilla build with Pango support and setting MOZ_ENABLE_PANGO as described upthread, I'd got Hebrew vowels to display correctly, i.e. within and around the preceding characters. According to what I've seen, Firefox 1.5 is supposed to have Pango support built in. However, it's rendering the Hebrew vowels between the characters, which is pretty much unreadable, and setting MOZ_ENABLE_PANGO makes no difference. Is there a configuration issue of some kind I'm missing, or is this a new bug in Firefox?
*** Bug 349532 has been marked as a duplicate of this bug. ***
Looks like this bug has been around for six years now, without anyone taking it too seriously. The suggestion of using a Tanakh (Bible) website to genetrate all possible conmbinations of consonants and vowels (= nikodot or nikodos = diacritical marks) will probably work for Hebrew, but not for Yiddish. The diacritical marks in Yiddish are different from those in Hebrew: there is only partial overlap. Furthermore, while Hebrew can be written without these marks (and read by proficient speakers), Yiddish cannot. In fact there is only a small number of letter/mark combinations in Yiddish, I think fewer than in, say, French. Fixing this problem in Yiddish is therefore not likely to be rocket science.
(In reply to John Clark, comment #81) > Looks like this bug has been around for six years now, without anyone taking it > too seriously. It's likely that none of the developers who volunteer to fix bugs have found this one interesting enough. If you feel it's important and you wish to improve the chances of it being fixed, then you might want to start a bounty. Prog.
It seems to work correctly with firefox 184.108.40.206. Was there switch to PANGO for text rendering?
This will be fixed when the new textframe code lands, or shortly afterwards.
I find that, at least on Windows XP Media Center Edition and Windows XP Professional, Hebrew diacritics work properly when I have "Install files for complex script and right-to-left languages (including Thai)" checked in the Regional and Language Options section of the Control Panel, and do not work properly when I do not.
Comment #85 worked for me. Problem solved. Thank you very much. John Clark.

I still see this bug in 18.104.22.168. What's more interesting is that i see a similar bug in the latest released binary Gran Paradiso alpha 5. But in Gran Paradiso it is slightly different. In Firefox 2 the vowel dot is somewhere in between its consonant and the next letter. In Firefox 3 alpha 5 the vowel dot is rendered correctly in relation to its consonant, but after the consonant there's a space which shouldn't be there. I attached three images which demonstrate rendering in Fx 2, Fx 3 and IE6. The words with vowel dots are accented with red.
The thing I think I figured out the other day: if a font doesn't itself have nikudes (nonspacing marks for vowel points, etc.), then Firefox tries to get them from other fonts. It does an admirable job finding them; however, it applies them in the wrong way, i.e., devoting a whole new character cell to them. You can see an example of this by selecting most of the "transparent" fonts on Windows, e.g., Miriam fixed transparent. So, using this approach, I could reproduce the problem of having "nonspacing" marks become spacing and consume their own character cell on all platforms (Linux, Macintosh, Windows).

(In reply to comment #90) > I still see this bug in 184.108.40.206. Yes, you would. As I said in comment 84, this will be fixed when the new textframe lands, which should be before Gran Paradiso Alpha 6. Checking "Install files for complex script and right-to-left languages (including Thai)" works for many cases on 220.127.116.11, but not for justified text, as used in http://haharoni.wordpress.com/2007/06/12/meuhedet-si/ When using fonts without vowel points on trunk with new textframe, the vowel points simply don't appear. I'll file a new bug about that.
Is this fixed now that new textframe is turned on?
It's fixed on Windows. I don't know what the story is on Mac, and on Linux it isn't 100% perfect, but it will be better to file new bugs for remaining issues.

Simon, have you filed a bug for vowel points not showing up if missing from a given font (i.e., not being substituted from another font), which you reported and said you'd file a bug for in comment #95? Thanks.
Thanks for the reminder: filed bug 385622.
