305394 - Thai characters not displayed with the correct font in <h1> elements

Status: VERIFIED DUPLICATE of bug 225217

(Core Graveyard :: GFX: Mac, defect)

Description

[Emmanuel Pietriga]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

Thai characters are not displayed with the correct font in the <h1> element
found e.g. at [1]. Note that thai characters are displayed correctly within
<p><a> elements inside the same page.

The <h1> problem occurs at least with Mac OS X 10.4.2/Firefox 1.0.6. It does
*not* occur with Firefox 1.0.6 under Windows XP (I haven't tested Linux). It
does not occur either with Safari 2.0 (probably not helpful, but just FYI).

Page at [1] is served as UTF-8, and it is valid XHTML 1.1.

Note also in the same page another less important bug: there is a lot of
whitespace between the words actually written in Thai and the closing
parenthesis (whereas there is no whitespace in the source).

Reproducible: Always

Steps to Reproduce:
1. load http://emmanuel.pietriga.free.fr/photos/thailand.php
2.
3.

Actual Results:  
Firefox displays this text for the h1 element (weird chars between the
parentheses instead of thai chars): Thailand (ราชอาณาจักรไทย)

Expected Results:  
Display thai characters.

This WFM since the 2005-03-23 trunk builds, due to the fix of bug 159809 (which
changed the default fornt for Thai to "Lucida Grande").

Reporter - notice that you can manually change your defaulty Thai fonts to
Lucida Grande - that should cause the page to display properly.

I'm not closing it as WFM since I think this should be displayed correctly even
when the default font is one which does not include Thai. The system should fall
back to a font that does have Thai.

There's a serious bug with Gecko's ability to handle certain Mac fonts,
including fonts for Thai (bug 225217, bug 246527, perhaps others).  As Uri
noted, we've worked around the for now in bug 159809, which wasn't fixed for Fx
1.0.x updates for some reason....

More appropriate to dupe to existing bug 225217....

It wasn't backported because the 1.0.x branch is a stable, security-fix-only branch.
