NAME

       unigencircles - Add dashed combining circles to a unifont.hex file

SYNOPSIS

       unigencircles combining.txt nonprinting.hex < unifont.hex > unifont-circles.hex

DESCRIPTION

       unigencircles  reads  a  unifont.hex file from STDIN, adds dashed combining circles to the
       hex strings for code points listed in "combining.txt" but not listed in "nonprinting.hex",
       and  writes  the  revised  set  of  glyphs in unifont.hex format to STDOUT.  The resulting
       combining character glyphs show the dashed combining circles that appear  in  The  Unicode
       Standard code charts.

       For   each  code  point  listed  in  the  "combining.txt"  file  but  not  listed  in  the
       "nonprinting.hex" file, unigencircles will superimpose a  single-width  dashed  circle  in
       glyphs  that  are  single-width (i.e., their hex glyph strings are 32 characters long) and
       will superimpose a double-width dashed circle in glyphs that are double-width (i.e., their
       hex glyph strings are 64 characters long).

EXAMPLE
