PC Screen Font
The PC Screen Font (PSF) format is a fixed-width bitmap font format originally used on the PC under MS-DOS. It was subsequently adopted and extended for Linux console fonts.
PSF has been extended to support Unicode. The .psfu file extension is sometimes used to indicate that the file includes Unicode mappings, though .psf files often have them as well.
Files begin with bytes
0x36 0x04 (version 1) or
0x72 0xb5 0x4a 0x86 (version 2). The former may be a reference to vfont format, the magic number of which is 0436 when converted to octal.
