[PATCH 2/4] test-lib.sh: add test_utf8() function

From: Yann Droneaud <yann@droneaud.fr>
Date: Jan 6, 2011, 14:22 UTC
Message-ID: <8559d90bff6fca1c18f1cbf3530f2f4cc695f9f4.1294312018.git.yann@droneaud.fr>
In-Reply-To: <cover.1294312018.git.yann@droneaud.fr>

test_utf8() checks for en_US.UTF-8 locale availability using lib-locale.pl. The function returns 1 if a locale was not found, otherwise it returns 0, set prereq UTF8 and export GIT_LC_UTF8 with the locale name.

If a test needs to use an en_US.UTF-8 locale, it has to call test_utf8() first. Then it can do tests based on prereq UTF8 availability and use LC_ALL=$GIT_LC_UTF8.
