man psfaddtable (Commandes) - add a Unicode character table to a console font
NAME
psfaddtable - add a Unicode character table to a console font
SYNOPSIS
psfaddtable fontfile tablefile [outfile]
DESCRIPTION
psfaddtable takes a console font in .psf format given by fontfile and merges it with the Unicode character table given by tablefile to produce a font file with an embedded character table, which is written to outfile if given, or else to standard output. Either fontfile or outfile (but not both) can be replaced by a single dash (-) to read from standard input instead. If the fontfile already contains an embedded character table, it is ignored.
TABLE FILE FORMAT
Each line in the tablefile should be either blank, contain a comment (preceded by #), or contain a sequence of numbers in either decimal (default), octal (preceded by 0), or hexadecimal (preceded by 0x) format. The first number on each line indicates the glyph slot in the font that is being referred to, this is between 0 and 0xff for a 256-character font and 0 and 0x1ff for a 512-character font. Any subsequent numbers on the same line are Unicodes matched by this specific glyph slot. It is permissible to have multiple lines for the same glyph.
