3 unihexfill \- Generate range of Unifont 4- or 6-digit hexadecimal glyphs
8 .I unassigned-ranges.txt
13 is a shell script that reads a list of code point ranges from STDIN
14 and produces filler glyphs of 4- or 6-digit code points on STDOUT.
16 The format of the input file is a combination of comment lines,
17 single code points on a line, and start/stop pairs of code points on
18 a line separated by a space. Comment lines start with a semicolon (';')
19 by convention. Start and stop code points are strings of hexadecimal
20 digits, by convention either four or six digits.
25 for each non-comment line in its input file. If a codepoint is less than
26 or equal to "FFFF" (i.e., 0xFFFF), a four-digit hexadecimal number is encoded
27 within the corresponding Unifont glyph as two digits on each of
28 two rows. Otherwise, a six-digit hexadecimal number is encoded as
29 three digits on each of two rows.
33 *.txt as input; *.hex as output.
35 In the Unifont source package, the file font/plane01/Makefile generates
36 Unicode Plane 1 hexadecimal filler glyphs of unassigned code points within
37 assigned scripts with this single-line command:
