Thanks for the advice. Situation is that I'm working on a project where
the PoDoFo is already extensively used, and can't simply switch to
another library.

I want to generate a pdf document, which contains strings in
several languages. Set of the languages (i.e. set of required
characters) can be determined only at generation phase, so I've
decided to use a font, which contains as much as possible
characters (http://en.wikipedia.org/wiki/GNU_Unifont in my case),
to represent any possible input language during the rendering of
the document by a pdf viewer.
The GNU Unifont isn't c_ommon at clients' workstations (which is
mostly under the MS Windows control), so I should to do some form
of font embedding. But I have conflicting requirement - documents
_should be as small as possible, so full font embedding isn't an
option (+ 3 Mbytes of overhead per document is too much for me).
I think that only possible option in my situation is to embed only
those glyphs which actually used in document - this is what I mean
under 'font subsetting' term.
Is it possible to make this using PoDoFo ? Or maybe there are
another ways to satisfy the requirements ?

You don't actually subset a CID font - since there is no such thing as a
CID font file.
A CID font is really a special way to encode/store font data in a PDF file
when having to deal with Unicode-based fonts. You can create a CID font
from a TTF or OTF font as part of subsetting it - though it's not required.
So backing this upŠ
What are you trying to achieve with PoDoFo that is blocking you?

Hi!
After some searching through the podofo code I suspect that subsetting
for the CID fonts isn't implemented (PdfFontCID doesn't implement
AddUsedSubsettingGlyphs etc.) and can be done just for the PdfFontType1
fonts (which doesn't support unicode). But there are mystic (for me)
PdfFontTTFSubset and PdfFontCache::GetFontSubset.
So, is CID fonts (unicode-aware) subsetting supported and what are
PdfFontTTFSubset and PdfFontCache::GetFontSubset for ?
Thanks!
