unihexfill NAME
---------------

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

unihexfill SYNOPSIS
-------------------

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

unihexfill 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.

unihexfill OPTIONS

There are no options.

unihexfill 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

unihexfill 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.
