From 9c94389c3ee02df891100b894c1790a524268d91 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Torsten=20B=C3=B6gershausen?= Date: Fri, 9 May 2014 23:51:44 +0200 Subject: utf8: make it easier to auto-update git_wcwidth() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 update_unicode.sh to update the table based on the latest Unicode specification files. Thanks to Peter Krefting and Kevin Bracey for helping with their Unicode knowledge.
