Sure, feel free.

If I got you right: are you thinking to force the use of a reader provided font, the closer to the one needed, the better?
And _that_ is the non trivial part, discovering the closer one?

The form fields already carry a font attribute; however in the produced PDF we need the PostScript name of the font, not just the family. For our own fontsubsets we simply define that name, for a system font we would need the correct PostScript name or the reader will end up with not finding the font.

The tricky part would be if we have to choose an encoding IMHO, this is trivial for western fonts (WinAnsiEncoding will do the trick), but there is no clear way for encodings other than ansi1252. But the PDF reference says, the encoding is optional, if omitted the "font's encoding" will be used, so perhaps there is no real problem here. I just worry about this fuzzy "encoding of the font" since e.g. most truetype fonts have a multitude of encodings builtin. But perhaps we can treat this as a black box and simply omit the Encoding entry of the font dictionary.

Just my 2 cents, pl
