From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.1) Gecko/20010607 BuildID: 2001060703 The characters look ugly in the toolbar, menus and dialogs, probably because of wrong font or font size on simplified chinese version of windows 2k. Reproducible: Always Steps to Reproduce: 1. On simplified chinese Windows, add a bookmark with a Chinese title. 2. Pull down the Bookmark menu and u will see the bookmark title 3.
It seems the size we pick is too small. German- where do we set the size for skin. It looks you pick a font size too small for CJK text. nhotta- please take a look at this. Is the size reasonable for Japanese these days? German- are you using size 10 and below? I agree the text is not readable.
Status: UNCONFIRMED → NEW
Ever confirmed: true
Both modern and classic set the font using what is set as system font. Please talk to skin master Hewitt (cc'd), if you need anything special here.
Japanese bookmark text looks fine on JA localized windows (I will attach a screen shot). But not good on US windows, probably it's system font related as german's comment.
Feng, is your system US version or you are using Chinese localized system?
I'm using Chinese localized windows 2000 professional.
ylong, do you have Chinese windows (I think the bug is about Traditional Chinese)?
I only have Simp. Chinese2k, I'll check it on Traditional Chinese window in lab later.
Actually, I just noticed the reporter was using Simp. Chinese2k. I got very similar result - the Chinese characters(kanji) not very nice, don't show same as in Japanese Windows(N6.1Ja).
>Both modern and classic set the font using what is set as system font. do you use the system setting for the size also ? I think the problem is not what font you use, but also what size you use. can you kindly point out where is it in the css for bookmark & menu ? Thanks.

This problem also occurs in the Linux for both traditional and simplified fonts (mozilla 2001072008). Occurs in bookmark, message list, and the message body.
Doesn't look like this is getting fixed before the freeze tomorrow night. Pushing out a milestone. Please correct if I'm mistaken.
Target Milestone: mozilla0.9.3 → mozilla0.9.4
*** Bug 92211 has been marked as a duplicate of this bug. ***
pushing out 1 milestone, not sure that I should own this, as I am not an expert on chinese charsets. Somebody on this list wants to own this?
0.9.5 is out the door. bumping TM up by one.

Let's get tao's opinion to see if we can do something here to look better in Chinese. ->tao
Assignee: yokoyama → tao
We need to use debugger to find out why this is happening: 1. are we returning the correct font size to the rendering engine? 2. if yes, is there prettier font available on the system but is not selected by the browser? Knowing the answer might help us make the decision as whether to fix the browser code or assign better font settings for UI (tweak "chrome://global/locale/intl.css" or default prefs.) assign to firstname.lastname@example.org for (1)
Assignee: tao → smontagu
The answer to (1) in comment 21 is "Yes". I think the problem is that on a non-localized system the default system font doesn't contain glyphs for Chinese, so we are using glyphs from some other font, resized to the size of the system font. Back to tao.
Assignee: smontagu → tao
Looks like this won't make it in for 0.9.6.
Bounce back to i18n group. CC l10n eng It seems to me the text layout engine needs a bit help to choose prettier fonts on native system. In theory, a native system should have sufficient font installed to render reasonable looking native scripts. Are we using the default system font size? How does Gecko determine what size to use? In other words, what's the order of precendence regarding font size: "intl.css", system font size, etc? Also, re-targetting to 0.9.7

>In theory, a native system should have sufficient font installed >to render reasonable looking native scripts. I agree with tao. >How does Gecko determine what size to use? I believe Gecko uses the Pref settings http://lxr.mozilla.org/seamonkey/source/modules/libpref/src/win/winpref.js Having said, I thought this bug is about the chinese text being ugly in the menu and dialogbox. Can somebody answer Franks comment (#12)? >can you kindly point out where is it in the css for bookmark & menu ?
I think bookmark css is http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/themes/modern/communicator/bookmarks/bookmarks.css However, I failed to find font facename setting and font size in the CSS Hewitt: where do we specify the facename and size?
The default font for all menus, (including the size), is set in |SetFont| http://lxr.mozilla.org/seamonkey/source/content/base/src/nsRuleNode.cpp#1635, which (on Windows) calls |SystemParametersInfo| at http://lxr.mozilla.org/seamonkey/source/gfx/src/windows/nsDeviceContextWin.cpp#358 css for menus is in http://lxr.mozilla.org/seamonkey/source/themes/modern/global/menu.css and http://lxr.mozilla.org/seamonkey/source/themes/classic/global/win/menu.css
Assignee: yokoyama → smontagu
The size of menu font can be control by Control Panel:Display:Apperance:Menu
I use yokoyama's simp chinese w2k system to look at it. The problem is the following 1. the modern theme listen to the control panel setting (not a problem) 2. in the simp chinese w2k system, if the appearance is set to "window classic" the font for menu is set to "Tahoma" 8. Which do not have Chinese glyph 3. in IE, when it set to "Tahoma" 8, it use a font fallback algorithm whihc pick up a nice fallback 4. in Mozilla, when it set to "Tahoma" 8, we SHOULD use the locale font setting for font fallback, but we don't for some reason. The real problem is the font fallback algorithm for lang group x-unicode
this is not a style sheet issue. This is a font fallback algorithm issue on window. Reassign to shanjian. As you can see, if user set the "Menu" font to "Song" then we will display correctly. This is because the "Song" have chinese glyph but tahoma do not. The problem is our fallback algorithm does not pick up Song while it should.
Assignee: smontagu → shanjian
shanjian- what is the order of font fallback when a specific font do not have the glyph ?
First we try the font name if specified by user, and then generic font using font family name. If still could not find a font, all system fonts will be tried in rather random order, and first one contains the glyph will be returned.
>First we try the font name if specified by user, and then >generic font using font family name. So... if the font-family is "tahoma" and the lang group is "x-unicode", and the system locale is "zh-CN", we should try the following 1. "tahoma" 2. the "serif" font of "zh-CN", 3. all other "serif" font for different langauge group 4. all other fonts, right ? (the reason 2 is "serif" font of "zh-CN" instead of "serif" font of "x-unicode" is because erik add some code in the nsLanguageAtomService to map "x-unicode" lang group to the locale lang group. However, I didn't see 2 happened. Do we pass "zh-CN" down as langgroup ? or "x-unicode" ? Which font we used ? Why?
Give me a minute and I will give you the whole picture about what's happening. Can you tell me where is the control panel setting?
Ok, here is what's happening. To be simple, it is not because we choose the wrong font, but because "we?" choose the wrong size. On my simplified win2k system, control panel shows default setting is "tahoma" with size 8, that is interpreted as height of "-11" in creating font. When this font is failed to display those chinese characters, global font is tried and "MS song" is found. But size "-11" make the font looks ugly. Selecting size "9" in control panel menu setting, problem will be gone. Selecting "Song" but keep size "8", problem is still there. Some additional detail, The lang group we are using is x-wester, not x-unicode. That is reasonable because the whole interface is English. If user using localized chinese UI, we should use "zh-cn" as lang group. (If not , that will be a bug.)
Status: NEW → ASSIGNED
Solution? Strictly speaking, this is not a problem of browser. We should honor control panel's setting, and we should keep all font looks the same size. It is possible to put in a hack in creating font. That is to use a slightly larger size for CJK font. But I believe many people may hate the idea and we will create more problems that solved.
I post a screen shot of IE with size 8 and size 9. As you might notice that they (MS) are using same size for Chinese characters, and different size for English. For further smaller size (6, 7), chinese character becomes sizable again.
>Some additional detail, >The lang group we are using is x-wester, not x-unicode. That is reasonable >because the >whole interface is English. If user using localized chinese UI, we should use >"zh-cn" as lang group. (If not , that will be a bug.) Ok, I got it. We add the font setting for the UI locale (user locale) to the generic list. Should we also add the system locale to the generic list after ? Look at nsFontMetricsWin.cpp FindGenericFont we first add the font and font-list of the langgroup to the list, and then we add the gUsersLocale's font and font-list to the list (if gUsersLocale is differ from langgroup) and then we call GenericFontEnumContext. Should we add the font and font-list of the system's locale before we call GenericFontEnumContext ? If we do so, then we will try simplified Chinese font first before try other fonts. This will make the English UI build run better on Chinese system. and also, we should try all font and font-list of other language group before we try global font. So... currently, the algorithm is 1. try the font user specify 2. try font and font list of the page's language group 3. try font and font list of the user's ui language group 4. try global font and I suggest we add 3.1 try font and font list of the system's language group 3.2 try font and font list of the rest language groups >On my simplified win2k system, control panel shows default setting is >"tahoma" with size 8, that is interpreted as height of "-11" in creating font. >When this font is failed to display those chinese characters, global font > is tried and "MS song" is found. on roy's chinese system, that is not exactly what we see. It seem's it is not using "MS song" but some other type face.
move this bug to m0.9.8
Target Milestone: mozilla0.9.7 → mozilla0.9.8
frank, it is "Song". All the difference we saw are because of size. I manually change the size during my debug session and it works. As for your suggestion about traversing lang group in find generic font. That looks reasonable to me. How to make it work efficietly is my concern. I believe it is doable.
>frank, it is "Song". All the difference we saw are because of size. That is not what I saw. I agree that size is one major issue. but one another issue is we didn't pick a reasonable font face neither. I belive we need to address both issues.
here is a trial patch
not sure the trial patch make thing better yet. Need to test on a system which reproduce the problem easily.
-> nsbeta1, it really ugly with Simplified Chinese windows including WinXP-SimpChinese interface.
Severity: minor → major
Actually, the above comment was on Multi-lingual WinXP with default language setting to Simp. Chinese. On real localized Simp. Chinese WinXP, the font will display fine.
nsbeta1+ may be we should do this in the system is Chinese and the font size it return is < 9, return 9
In IE, they only use size 9 font to display size 8 characters for Chinese, all English strings remain 8. Similar things does not happen if size < 8. That's say if request size is 6,7,etc, they do display those chinese characters as requested. AND this happens for UI font only. In html body, all request size if honored, size 8 chinese font is not allign to 9. I guess the problem should exist beyond localized chinese win2K. If we implement a generic solution, (eg. align size 8 to 9 for chinese characters), we will break something else. This is really a headache.
push to 1.01
ftang - don't you think this should be a nsbeta1+? If we're going to make a Chinese product, we want it to look okay.
FYI: (haven't check WinNT-CN and WinME-CN though) Chinese font look good: WinXP-CN, Win98-CN Font has the problem as showing in this bug: WinXP-Multi-Lingual UI when setting SimpChinese as default language, Win2000-CN and other non-SimpChinese windows.
renominate as nsbeta1 - we still see it on many windows system, especially on Win2k.
Yuying, is this nominated again for Win2k? Is it okay for other Window platforms?
It's for both - win2k including win2k-SC, WinXP-multiligua UI even you setting locale as SC, any other non-SC systems.
we should release note this. People can change their font size by changing "Control Panel:Appearance". They can select a different font or increase the font size. The quality of the font is not really in our control. This is really a MS window's bug instead of an application bug. nsbeta1- and please release note it.
Get together with Frank and Xianglan, Frank did some more research on seetins between system and our prferences, we might have a solution for this. Renominate as nsbeta1 again.
so... we decide to do the following, in the simplified chinese system, if the control panel return 9 or smaller value, return 9 instead. to implement that. we need to add code to mozilla/gfx/src/windows/nsDeviceContextWin.cpp GetSysFontInfo method and right before CopyLogFontToNSFont (or in that function) check the height and when the size is too small (make sure we cover both the positive case and negativie case) round up to equal to 9 if it is running on the simplified chinese system (GetACP() == 936 ) reassign to ftang as adt 2
I'm using win2k and the default language is traditional chinese. I did not use chinese menu in mozilla because chinese font in the menu is very difficult to read. Today I tried to change the font setting in mozilla. I changed all the fonts for unicode to mingliu (a font for traditional chinese). After restart, the display of chinese menu is much better. The font is the same as the screenshot from http://www.csie.ntu.edu.tw/~b7506051/mozilla/screenshot.html I'm not sure whether it only works in my computer. In my first trial, I needed to delete Arial Unicode MS font to make things happen.
shanjian, can you r=
We should only replace 8 with 9, and keep rest size (7, 6, etc) unchanged.
anything below 9 is too small and ugly.
I knew. But any size below 8 must be manually selected by user. If they do it, they must have a reason and we should respect their choice. Size 8 is special because it is a default, and this default size is not a good choice.
shanjian, this value is control by the control pannel. And the user may not select a specific font size to change it. If user select a differen APPEARANCE THMEM, the font name and size may change. So what the user may do is to change from "Window Traditional" to "Window XP" theme, and the size could be change. or select from "Normal" to "Small" the size could be changed. remember, this code will only be hit when we access the info from the control panel, this code does NOT impact the size from our preference window, nor any direct reference in css or html.

all the documentation refer to 936 directly. There are a SNA header file define CP_936, but it will create dependency on a wrong header file.

Attachment #85338 - Attachment is obsolete: true
shanjian: can you look at my latest patch and try on your chinese system?
Frank, I tried your patch on my SC2k. You need to make some modification before it will work. You need to adjust the size before converting to twips. After that, all font in menu, dialog, etc use 9 point font instead of 8 point. When we running mozilla english version on Chinese system, do we really want all those fonts in 9 points? I am kind of hesitant to such a change.
the fix in trunk is not good. should back it out.

Comment on attachment 87308 [details] [diff] [review] new patch are you sure you should check and change it before the NSIntPointsToTwips? should aFont->size be limited to 9 or pointSize be limited to 9? I remember in my computer I got pointSizet = 11 but NSIntPointsToTwips convert it to 8. Can you confirm that? Will it change depend on the screen res?
I verified this on my box, pointSize should be limited to 9. I also tried a different resolution, it works the same way.
