I wish if this Werner's post is appropriate to continue
the discussion of the font format to be supported by
Fonty Python.

Yet I'm not sure the target application that Fonty Python
manages the fonts for, but considering the fontconfig's
limitation, I think the first group for FP would be the
font files with Unicode interfaces and outline (not bitmap-
only) fonts. So CFF OpenType would be the first candidate.

# fontconfig insists as if it supports bitmap fonts like

I'm not sure if Type42 (an encapsuled conversion of TrueType
font for PostScript language) is worthful. The handling of
Type42 is similar to Type1 font, so it may easy to support
after Type1 is supported. But I don't know any font package
(or products) including an independent file in Type42 format.

CID-keyed font files should be avoided at present. They
should be used with other files to attach character encoding
interface - they don't have simple Unicode interface.
