Status: RESOLVED WONTFIX

(Core :: Internationalization, defect)

Description

[Andreas Prilop]

User-Agent:       Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.7.3) Gecko/20040919
Build Identifier: Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.7.3) Gecko/20040919

The Yiddish digraphs U+05F0, U+05F1, U+05F2, for example
on http://www.google.com/intl/yi/ , display as question marks
in Mozilla (Solaris) because they are outside ISO-8859-8.
But they could be easily displayed using Hebrew characters
U+05D5, U+05D9 from ISO-8859-8 fonts.

Reproducible: Always
Steps to Reproduce:
1. http://ppewww.ph.gla.ac.uk/~flavell/unicode/unidata05.html
2. Look at 05F0, 05F1, 05F2
Actual Results:  
Characters 05F0, 05F1, 05F2 are displayed as question marks
in Mozilla on Solaris.

Expected Results:  
Display Yiddish digraphs using Hebrew characters
U+05D5, U+05D9 from Solaris ISO-8859-8 fonts.

Perhaps, we have to add them to our transliteration table so that when glyphs
for them are missing, we can fall back to rendering them with glyphs for U+05D5
and U+05D9.

I thought I had commented here a few months ago. The original IBMBIDI code did
something like that (not for these specific characters, which for some reason
unknown to me don't have any decomposition defined in Unicode), but it didn't
pass review because the output from the transliterator is required to be ASCII.
See bug 80151.

Gfx has been rewritten not to need transliteration.
