unigenwidth \- Generate C code for POSIX wcwidth and wcswidth functions
.SH SYNOPSIS
.br
.B unigenwidth
.I unifont.hex combining.txt
.SH DESCRIPTION
.B unigenwidth
reads a collection of glyphs in Unifont's .hex format,
then reads a list of combining characters as a hexadecimal list.
From these two files, it produces C code to implement the POSIX
.BR wcwidth(3)
and
.BR wcswidth(3)
functions.  The format of these definitions is based upon
POSIX 1003.1-2008 System Interfaces, pages 2251 and 2241, respectively.
