TextWidth is already in fpTTF / TFPFontCacheItem.

Actually, IMO it should be the programmers responsibility to include TTF 
files for default PDF fonts if he wants to use TTF features on them. And 
your problem is solved :)

+  For now fpPDF can render only ASCII glyphs for standard fonts. Is 
this a limitation of the PDF format? If yes, then the default PDF fonts 
have to be embedded as TTF anyway in many cases anyway.

fpTTF is better, IMO. It should be made on TTF-level, not PDF.
It would be great if you could move it to fpTTF - it would spare me some 
time for other things. Although it shouldn't be that hard, but it's 
still a plus :)
