Using the country.cfg configuration file

The afpfont.fnt, alias.fnt, cpdef.fnt, csdef.fnt, icoded.fnt, and coded.fnt font configuration files can be renamed using a different extension by adding a country.cfg configuration file in the font directory. The font directory path is specified either by the -n flag or the Font_path entry in the a2pxopts.cfg file.

The contents of the country.cfg file is Country=zzz, where zzz can be one of these values: cht, chs, jpn, kor, fnt, matching the file name extension. The default extension is .fnt.
