378105 - Need to update default fonts for Indic scripts

Status: RESOLVED FIXED

(Core :: Internationalization, defect, P2)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1
Build Identifier: 

There are two parts to the issue.

1. Monospace, Sarif, San sarif distinctions valid for Latin scripts does not Tamil - Latha
have much merit in Indic scripts. So the font lists like font.name-list.serif.x-devanagari, font.name-list.monospace.x-devanagari should have same list of Fonts.

2. Microsoft has released following Indic fonts for XP SP2. The lists should high priority for those fonts.

Devanagari - Mangal
Gujarati - Shruti
Gurumukhi - Raavi
Bengali - Vrinda
Tamil - Latha
Malayalam - Kartika
Kannada - Tunga
Telugu - Gautami

The decreasing order of priority should be:
"<Fonts common in user community>, <XP fonts>, <Generic font>"

For example, Malayalam font configuration should look like:
pref("font.name.serif.x-mlym", "Rachana_w01");
pref("font.name.sans-serif.x-mlym", "Rachana_w01");
pref("font.name.monospace.x-mlym", "Rachana_w01");
pref("font.name-list.serif.x-mlym", "AnjaliOldLipi, Kartika, Arial Unicode MS");
pref("font.name-list.sans-serif.x-mlym", "AnjaliOldLipi, Kartika, Arial Unicode MS");
pref("font.name-list.monospace.x-mlym", "AnjaliOldLipi, Kartika, Arial Unicode MS");

Updating these lists will not only improve our font selections but also improve performance...  On windows at least, we can now support font prefs for a bunch of these languages that we didn't support before.

Comment 3

[Simon Montagu :smontagu]

Do we have a mechanism to define Vista-specific prefs for the fonts that are newly available there?

Comment 4

[Stuart Parmenter]

Not specifically.  We can certainly put them first in our font-list prefs and we'll skip them if they're not available but that won't help us for the default font for that language if it is available ahead of the font-list prefs.  We could expand the default font stuff to support multiple fonts too I suppose.

For languages that we haven't previously supported, we can just add prefs based on the languages listed in here: http://mxr.mozilla.org/seamonkey/source/gfx/thebes/src/gfxWindowsFonts.cpp#752
I used three letter codes for all the languages we don't have prefs for already and we could change them to be something else if we wanted.

Simon can you take this?

Moving to P2, can we get a fix ASAP, please?

Attachment: Patch v.0

This has got all the necessary infrastructure, but we may want to tweak the actual font lists some more. It also has l10n impact, with four new strings in the fonts preferences dialog, but it shouldn't be too serious, because the same strings already exist in languageNames.properties.

Patch v.0

-    { "LANG_KASHMIRI",   "x-devanagari" }, // kas
+    { "LANG_KASHMIRI",   "kas" },

Why this change?  I'm pretty sure that for that one uniscribe was giving me that for things that looked pretty devangariish.

Is Code2000 better than Arial Unicode MS for most of these?

this patch generally looks OK to me.  we'll need to get string change approval

Comment 9

[Simon Montagu :smontagu]

http://www.ethnologue.com/show_language.asp?code=kas and http://www.omniglot.com/writing/kashmiri.htm both say that Kashmiri is written in Arabic script.

Comment 10

[Simon Montagu :smontagu]

For the ui-review, note that I've also alphabetized the list of languages in the fonts pref dialog. I'm in two minds about this: for l10n it will mean replacing the current apparently random order by a different apparently random order, so it might be better to make an attempt at a categorized ordering, with European languages together and Asian languages together.

Comment 11

[Simon Montagu :smontagu]

Attachment: Patch v.1

Corrected some typos, removed Code2000 from the lists for languages that it doesn't support, and added a default values for font sizes for all lang-groups on all platforms to all.js. (The last is possibly a bit out of scope here, but I noticed when checking that I hadn't broken anything on other platforms that the fonts pref dialog is butt-ugly on Linux if any default value is missing).

=> checkin-needed, because I probably won't be able to check this in before string freeze.

Comment 14

[Simon Montagu :smontagu]

Attachment: String changes separated out

For convenience, this is the new strings from the previous attachment in a separate patch, and could be checked in on its own to make string freeze.
