[ft-devel] Convert glyphs to/from CIDs?

[Derek Clegg]

I have a CID-keyed font, and I need to obtain the underlying glyphs in  
the font for CIDs and vice-versa.  Is there a public function which  
does this already?

If not, I'm happy to add it.  I presume the best place to declare it  
would be in FT_CID_H since it's a CID-specific function?

As an aside, I was surprised to find that the "num_glyphs" field in  
FT_FaceRec doesn't provided the number of CIDs for CID-keyed fonts,  
but instead the number of glyphs.  This seemed to be an odd mismatch  
between this value and the behavior of "FT_Load_Glyph" where the glyph  
index is the CID.  Is there a way to obtain the number of CIDs in a  
CID-keyed font?
