Right. The information I gathered so far is that there is no UTF-8
locale available for X-windows. At least not for most people on
existing systems. Is it possible at all (under development)?
The XIM produces characters as "compound strings". The application
receives it in the current locale, with an implicit conversion. Since
an UTF-8 locale currently can't be used, I have to use the trick to keep
the locale set to euc-jp, for example, and translate it with iconv() to
UTF-8.
Vim then internally works with UTF-8 (this can be set with the
'charcode' option and selecting a Unicode font). This is a bit tricky,
working with text in another encoding than the current locale, but I
think it will work. Vim uses its own functions to deal with UTF-8, it
doesn't depend on mblen(), wcwidth(), etc.
A better solution would be that the locale is set to UTF-8. The
X-windows functions should then automatically translate the compound
string to UTF-8. Then no translation is necessary in the application.
This is for later.
Note that my conclusions have not been verified.
