If uim-xim gets "EUC" by XIM_ENCODING_NEGOTIATION (ex. LANG=ja on Solaris10),
uim-xim sends no XIM_COMMIT.
XIM_COMMIT does not appear in uim-xim --trace-xim output
when a string is committed.

When encoding is "EUC", iconv_open() fails and uStringToCtext() returns NULL.

This patch changes XimIM::set_encoding() to make "eucJP"
from 'encoding' and 'mLangRegion' when 'encoding' is "EUC".
