From 06e66572fd5541df0d1349cac2b404c3b9e446ee Mon Sep 17 00:00:00 2001
From: Jarkko Hietaniemi <jhi@iki.fi>
Date: Sun, 2 Mar 2003 13:34:13 +0000
Subject: The -CI cannot be easily tested under UTF-8 locale with the t/test.pl
 (the 'stdin' data gets doubly UTF-8-ied). Also other small tweaks in the -C
 neighbourhood.
