Problem with unicode character representation with the pbPDFModule by Thorsten1867
Posted: Fri Aug 27, 2021 1:30 pm
Hello, a bit desperate I try to use the great pdPDF module from Thorsten1867 to embed Unicode fonts in a PDF to be able to use e.g. the Cyrillic character set (U+0400 to U+04FF).
The sample program from Thorsten (pbPDF-EmbedFont.pb) with the font Lucida Sanc Unicode (l_10646.ttf ) works, but does not support the styles bold, italic or bolditalic. With every other font tested so far there are the following problems:
1. a black square with a white cross or a small black square is placed in front of each string and
2. with some fonts the following message appears additionally (at least in Adobe Acrobat): "In the font [here the font name] the value for /Flags is incorrect".
3. as a side effect I noticed that "PDF::Bookmark" does not support Unicode (or I don't know how). Here the Cyrillic characters are output as question marks.
Has anyone ever gotten a font with multiple styles with Unicode characters to work.
To understand the problem I have attached the pictures and a small example program. For testing please copy this together with the "ArialMT" fonts (arial.ttf/ariali.ttf …) from c:\windows\fonts\ into the examples folder of the pdfModule.
I hope someone has an idea or even a solution for the problem.
