You have to filter out IMEngines based on GTK+'s internal
encoding UTF-8, rather than current locale's encoding. My patch
performs so.

"current locale's encondig" makes no sense for
gkt-immodules. GTK+'s internal string encoding is fixed to UTF-8
regardless of current locale's encoding.

I want to use UTF-8 IMEngines on ja_JP.eucJP locale. Your code
filters out my necessary engines such as uim-anthy.

Yes, I know. Whether keys are sent back or not is not important
because both are useless. To eliminate the (context_scim->impl
== NULL) condition caused by locale dependency is what have to
do.
