NAME

       uniunmask - XOR bits or substitute glyphs in a GNU Unifont file.

SYNOPSIS

       uniunmask [-iinput_file] [-ooutput_file]

DESCRIPTION

       uniunmask reads a GNU Unifont .hex file.  As it reads the font file, it scans for code points matching entries in the "masks.hex" and "sub-
       stitutes.hex" files.  "masks.hex" and "substitutes.hex" are also in GNU Unifont .hex format, ordered by Unicode code point (the hexadecimal
       number to the left of the colon on each line).

       If  a code point is encountered from "substitutes.hex", the input code point in the original .hex file is ignored (as is any entry with the
       same code point in "masks.hex") and the glyph from "substitutes.hex" is written to the output file.

       Otherwise, if a code point is encountered from "masks.hex", the input glyph in the original .hex  file  is  XORed  with	the  bits  in  the
       "masks.hex" entry.  The result of this XOR operation is written to the output file.

OPTIONS

       -i	   Specify the input file. The default is stdin.

       -o	   Specify the output file. The default is stdout.

FILES

       masks.hex, substitutes.hex, *.hex GNU Unifont font files

BUGS

       No  known  real	bugs exist, except that this software does not perform extensive error checking on its input files.  If they're not in the
       format of the original GNU Unifont hex file, all bets are off.
