OK. So I created simple font with two ligatures: one with
ZWJ and one without.

And guess what. The ZWJ appears as unknown character and 
only the ligature without ZWJ works.

[XeTeX] BUG: ZWJ ignored? (Re: Fontspec and SBL Hebrew: Possible Bug?)

2010-11-20 Thread Petr Tomasek 

Hello!

Has this bug been solved somehow?


My XeTeX seems to ignore ignore the ZWJ character completely
(at least when script=hebr). I tried to edit some font
and created custom ligatures. If the ligatures where done
with ZWJ, they didn't work. As soon, as I removed the ZWJ
from the ligature definiton, the litagure started to work!

This did happen with 'ccmp', 'dlig' and 'rlig' GSUB tables.

My XeTeX version (on Linux):

xetex --version
XeTeX 3.1415926-2.2-0.9995.2 (Web2C 7.5.6)
kpathsea version 3.5.6dev

(I would like to try a newer version of XeTeX, possibly from
the SVN, but the last time I tried it, it didn't compile...)

Thank You!
