Date: Thu, 02 Sep 2004 01:06:23 +0200 From: Ivo Danihelka Subject: [SDL] [PATCH] Fixed XLocaleNotSupported in utf8 code there exist X server configurations which does not support locales. They even does not support conversion from utf-8 textList to utf-8 textProperty. This patch fixes such situations. It is my bug because I submitted the previous support for utf-8.
