utf8: make it easier to auto-update git_wcwidth()
The function git_wcwidth() returns for a given unicode code point the width on the display: -1 for control characters, 0 for combining or other non-visible code points 1 for e.g. ASCII 2 for double-width code points. This table had been originally been extracted for one Unicode version, probably 3.2. We now use two tables these days, one for zero-width and another for double-width. Make it easier to update these tables to a later version of Unicode by factoring out the table from utf8.c into unicode_width.h and add the script to update the table based on the latest Unicode specification files. Thanks to Peter Krefting <> and Kevin Bracey <> for helping with their Unicode knowledge. Signed-off-by: Torsten Bögershausen <> Signed-off-by: Junio C Hamano <>
