User-Agent: Mozilla/5.0 (Macintosh; U; PPC; en-US; rv:1.2.1) Gecko/20021130 Build Identifier: All current mozilla browsers If the OS X 10.3 version of the Thonburi Thai font is installed, no Mozilla-type browser will display Thai. Instead, they display the MacRoman characters corresponding to the TIS-620/MacThai hex representing the underlying Thai text, even when this text is encoded as UTF-8. No problem can be found with the font, but somehow it seems to trigger a bug in Mozilla's Thai rendering. You can also contact Deborah Goldsmith at Apple (goldsmit@apple.com) for her reading of the problem. Reproducible: Always Steps to Reproduce: 1.Make sure OS X 10.3 Thonburi font is installed. 2.Point Mozilla browser at site with Thai (e.g. www.columbia.edu/kermit/utf8.html) 3.Try to read Thai text Actual Results: I got MacRoman gibberish. Expected Results: Displayed proper Thai script.

Hmm. that's odd. Mozilla and Camino on Mac OS X don't make use of ATSUI (well, it uses it a little) so that I expect Thai text not to be properly shaped, but hex string corresponding to MacThai/TIS620 encoding of the underlying text ? Wow, that's .... There's a bug filed for the CTL issue(bug 205476 and bug 121540). See also http://www.mozilla.org/releases/mozilla1.5/known-issues-int.html I wish I had a Mac so that I can fix this and other complex text rendering issues on Mac OS X...... Anyway, Tom, could you attach a screenshot? re Thonburi font. Do you know what kind of font that is? Is it an AAT font with mort table for Thai shaping? Do you know what CMap tables are included in the font?

And he also wrote that thonburi font doesn't have any CMap table (wtih PID=3).
As he wrote, that shouldn't matter.

Tom, you don't have any problem using the font in other applications, do you? (TextEdit and safari for instance. ) It looks like somehow Mozilla uses MacRoman Cmap instead of MacThai Cmap.

The problem only occurs with Mozilla or any browser using the same engine, and not with any other app as far as I know.
Still a problem with Firefox 1.0. Safari renders correctly. Is there a workaround? Maybe a different font?
(In reply to comment #7) > Is there a workaround? Maybe a different font? Well, the work-around is to set your Thai font preferences to use Lucida Grande (or XXX.serif, XXX.sans-serif, XXX.monospace to match the XXX.fantasy and XXX.cursive, in which case they will fallback to Lucida Grande anyway). See my bug 159809 comment 25 and following for my unschooled speculation.

This was FIXED on trunk by cairo and the checkin for bug 299222. There are still a couple of bugs on 10.5 with certain Thai fonts; they're filed.
