Several years (and a couple versions of xetex) ago, we used xelatex to
typeset UTF-8 texts with Bengali text, using the Rupali font. I
resurrected the files and re-ran xelatex, but now something very odd is
happening: all the Bengali text is coming out as Roman (ASCII, mostly)
glyphs in the PDF. The glyphs overlap in odd ways; I'm guessing that
the roman glyphs are being typeset according to the width of the Bengali
characters (some of which are zero width or do other odd things, like
wrap around the preceding character). Also, when I select some text in
the PDF and copy and paste it into some other app, I get the Bengali.
The problem does not appear to be with my source file: if I substitute
another Bengali font (Lohit Bengali), the Bengali comes out just fine.
Specifically, if I replace
\newfontinstance\bengalifont[Script=Bengali]{Rupali}
with
\newfontinstance\bengalifont[Script=Bengali]{Lohit Bengali}
the problem goes away.
I can create a minimal example if that would help, but I thought I'd
start with this simple query. Has anyone ever seen anything like this?
XeTeX 3.1415926-2.2-0.9995.2 (TeX Live 2009)
The Rupali font has not changed since the last time we used it
successfully; the file is still
Rupali_01-02-2007.ttf
