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.
