Subject: [PATCH v3 5/9] grep/pcre: prepare locale-dependent tables for icase matching
Date: Tue, 14 Jul 2015 20:24:36 +0700 [thread overview]
Message-ID: <1436880280-18194-6-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1436880280-18194-1-git-send-email-pclouds@gmail.com>
[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain; charset=UTF-8, Size: 2366 bytes --]
The default tables are usually built with C locale and only suitable
for LANG=C or similar. This should make case insensitive search work
correctly for all single-byte charsets.
