Our web application generates PDF files from HTML pages on the fly, using the Flying Saucer/xhtmlrenderer library. Unfortunately, the source text may contain certain unicode characters (the cyrillic alphabet, for example) which are not included in the font we use for this. Changing to another font is not an option because of corporate design issues.
Ideally, I would like to specify a fallback font that contains a wide range of characters (such as Bitstream Cyberbit) and use that only for those glyphs that cannot be found in the original font. Is this at all possible, and if so, how?
Thanks in advance for any pointers!
