From afeb6fcb7d94157808a9290226adbadd42a824ec Mon Sep 17 00:00:00 2001
From: Timo Sirainen <cras@irssi.org>
Date: Fri, 15 Feb 2002 13:38:24 +0000
Subject: [PATCH] /SET term_type 8bit|utf8|big5 - Removed --with-big5 configure
 option, it's now included the same way as utf8, though i'm not sure if it
 really works but at least it should partially :) Input line is now internally
 using 32bit chars but it's converted to 8bit chars for external use. Text
 buffer supports only 8bit + utf8 for now.
