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.
