NAME

       unihexfill - Generate range of Unifont 4- or 6-digit hexadecimal glyphs

SYNOPSIS

       unihexfill < unassigned-ranges.txt > filler-glyphs.hex

DESCRIPTION

       unihexfill is a shell script that reads a list of code point ranges from STDIN and produces filler glyphs
       of 4- or 6-digit code points on STDOUT.

       The  format  of  the  input  file  is  a  combination of comment lines, single code points on a line, and
       start/stop pairs of code points on a line separated by a space.  Comment lines  start  with  a  semicolon
       (';')  by convention.  Start and stop code points are strings of hexadecimal digits, by convention either
       four or six digits.

       unihexfill invokes unihexgen for each non-comment line in its input file.  If a codepoint is less than or
       equal to "FFFF" (i.e., 0xFFFF), a four-digit hexadecimal  number  is  encoded  within  the  corresponding
       Unifont glyph as two digits on each of two rows.  Otherwise, a six-digit hexadecimal number is encoded as
       three digits on each of two rows.

OPTIONS

       There are no options.

FILES

       *.txt as input; *.hex as output.

EXAMPLE

       In  the  Unifont  source  package,  the  file font/plane01/Makefile generates Unicode Plane 1 hexadecimal
       filler glyphs of unassigned code points within assigned scripts with this single-line command:

              ../../bin/unihexfill < unassigned-ranges.txt > unassigned.hex

BUGS

       No  known  real  bugs  exist,  except that this software does not perform extensive error checking on its
       input file.  Any line that appears to begin with a hexadecimal digit is fed to unihexgen.
