So that means that 
	downmodels_uni0338
cannot be parsed, in particular 
	downmodels

Looking into the parseCharName routine it seems because it cannot find
an unicode name nor that it looks like a proper name.

I would not say that this is an error. THere are many glyphs not recorded
in the unicode standard.

No, I still disagree. It is not a PDF syntax error. iT is a mistreatment
of poppler. Only because it cannot parse a charname does not mean that
it is invalid, I guess.
