In my perception, pango requires actual font file (.otf, .pfb etc.).
If there is no font files, pango can't render anything.
Even if there is only font metric files (.afm, .pfm, .tfm etc.),
pango can't handle it.

Moreover, in my experiment,
pango can't handle the ligature of PostScript Type1 font (.pfb with .afm
or .pfm).
It can handle the ligature of OpenType font (.otf).
