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.
