You can convert your BDF/PCF fonts to the "X11 bitmap only sfnt (otb)"
OpenType format[1], which harfbuzz does support[2]. As far as I know,
there are no tools that do this easily. (There are a few old projects on
github that might give a starting point like bdf2ttf). You can probably
script fontforge, though. I think it should also be possible to put all
different bitmap sizes and codepages in a single file, but that might
require more manual work.

Adobe Type1 (PostScript) fonts can be converted to OTF with the Adobe
Font Development Kit for OpenType (AFDKO)[3] (The AUR package is out of
date). This format should be readble by harfbuzz as well.

      bitmap-only OpenType fonts."
