Sorry Svetlana, but it is hard to help you, if you just post a piece of
code and say that it does not work. Why can't you get the GlyphID?
Exception? Does it return 0 all the time? Is the font embedded?
I strongly suggest that you debug this yourself. PoDoFo's C++ code should
be easy to understand for any programmer. What is necessary though, is some
PDF knowhow! PoDoFo is a low level PDF library and therefore requires that
its users somehow understand the basics of PDF. Especially if you work with
fonts, this is mandatory, as fonts in PDF is pretty complex topic. That's
also why I could thing of tons of issues, why this won't work.
Best regards,
Dominik
