You have to use the cmap.

This is the wrong solution.  TrueType fonts are *not* handled by
glyph names but with character codes only.  The glyph name
information is optional; there are a lot of fonts which don't have
the corresponding font table.

The correct way is to activate a Unicode cmap (i.e. PID,EID=3,1), then
convert the character code of your encoding to Unicode, and finally
using FT_Get_Char_Index() to convert the Unicode encoded character
into a glyph index.

Yes.  It makes not much sense for other font formats.
