Subject: [PATCH 06/11] grep/pcre: prepare locale-dependent tables for icase matching
Date: Thu, 23 Jun 2016 18:29:02 +0200 [thread overview]
Message-ID: <20160623162907.23295-7-pclouds@gmail.com> (raw)
In-Reply-To: <20160623162907.23295-1-pclouds@gmail.com>
[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain; charset=UTF-8, Size: 2333 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.
