Description Nicholas Shanks 2009-03-13 05:00:08 PDT
The website http://urdunews.net/ uses EOT/WEFT to overcome the unification in Unicode of Naskh and Nasta'liq (akin to Han unification for CJK that we're more familiar with). It is not acceptable to present Urdu in the Naskh script used for Standard Arabic. Since many computers don't have a Nasta'liq font installed, this site tries to provide one via EOT.

Note however that
a) The OpenType font used by the site doesn't work on Mac OS X, so supporting it won't help
b) It cannot be transcoded to Unicode (bug #22339), because it already is Unicode
c) The only Nasta'liq font I know of for Mac OS 10.5 is the QuickDraw GX font Nasta'liq Navees
    i) http://scripts.sil.org/Nastaliq_Download (Warning: causes crashes on 10.4 and below)
    ii) http://en.wikipedia.org/wiki/Nastaliq_Navees (screenshot; disclaimer: I wrote that article)

The best solution would be to ship a Nasta'liq font with the OS (perhaps Apple could buy that one from SIL), and have ur (Urdu), ps (Pashto) and fa (Farsi) use that font, in the same was as CJK fonts depend on language.

This font now works flawlessly in Snow Leopard. In Leopard it rendered one character (ە) incorrectly.

Is there a Radar bug tracking this?

Not to my knowledge. I haven't filed one.

Is this still an issue?
