Re: Passing unicode characters

["Mehdi Omidali" <mehdioa@gmail.com>]

Dear Mojca,
Thanks for your complete answer. In fact, in persian (and maybe
arabic) documents, we need every digit be in persian, like chapter,
section, figure, and even formula numbers (most of the people even
prefer persian digits in formulas which is possible in xetex).
As you know, the Mapping=farsidigits in a font definition works
perfect in xelatex.
Best wishes.
