163966 - Need to support sun.unicode.india-0 font encoding for 8 Indian languages

Status: RESOLVED WONTFIX

(Core :: Internationalization, defect)

Description

[Prabhat Hegde]

sun.unicode.india-0 is the font encoding of the Indian language font for Sun
platform. This font will be available for free download at Sun GADC web site in
the next few weeks. As indian font encodings are not standard, the only way to
support it on platforms (and releases) that do not support OpenType font (and
interested in backward compatibility) is to come up with a new font encoding.
This encoding is Unicode + PUA and is a single font encoding that supports 8
indian languages, Hindi, Telugu, Kannada, Tamil, Gujarati, Punjabi, Bengali and
Malayalam.

Linux and Solaris systems that use sun.unicode.india-0 font would benefit from
this. OT fonts are not yet popular in India and hence this feature is not as
useless as many of you may believe.

[Masaki Katakai]

Verified the patch works on Solaris and Linux.

Also I have put examples to enable "Hindi" font selection
on preference dialog. Will this be generic? I mean that
this "Hindi" menu will become available on all platform?
I haven't tried on Windows but if anyone knows how to make
"Hindi" to *NIX specific, please let me know.

[Masaki Katakai]

Is "hi_IN" good naming for language group? There is no lang group that
uses _. How about "hi-IN" ?

Comment 7

[Prabhat Hegde]

Sure hi-IN is fine.
