unigencircles(1) 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

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

FILES

*.hex files for Unifont glyph data

font/ttfsrc/combining.txt for combining code points

font/plane00/nonprinting.hex for non-printing code points
