psfjoin [--psf1] [--psf2] INPUTFILE [INPUTFILE ...] OUTPUTFILE
psfjoin concatenates one or more PSF files. The files in question must all have the same character size. Characters from fonts other than the first have their Unicode mappings ignored. This program was intended for use in generating 512-character PSF1 files, where the second 256 characters have the same meaning as the first but are drawn in a different style.
Force output in the PSF1 format.
Force output in the PSF2 format.
