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 exten-
