getunimap

GETUNIMAP(8)							       Linux							      GETUNIMAP(8)

NAME

       getunimap - dump the unicode map for the current console to stdout

SYNOPSIS

       getunimap [ -s ] [ -C console ]

DESCRIPTION

       The getunimap program is old and obsolete. It is now part of setfont (1).

       The getunimap program outputs the unicode map (also called a "Screen Font Map") for the current console to standard output.

       The  -C	option may be used with Linux 2.6.1 and later to get the map for a console different from the current one. Its argument is a path-
       name.

       The output of getunimap is of the form

		   0xAA U+1234 # comment

       where 0xAA is the font character code and U+1234 is a unicode character, that if displayed, will be displayed using glyph 0xAA in the font.
       Many unicode characters may be mapped to the same glyph.
       the Hash symbol # is used as a comment delimiter; characters after a hash sign (to the end of the line) are comments.

       The -s option will sort and merge elements, sorting on font character.  Hence, it will produce output of the form:

		   0x22 U+1234 U+5678 U+3456
		   0x23 U+0023

	    etc., listing the multiple unicode characters that map to a font glyph.

       The output of getunimap is of the form accepted by setfont and psfaddtable

SEE ALSO

       psfaddtable(1), setfont(1).
