	I can say even more. Even if user have broken locale or/and broken input he 
can write non-English letters anyway. I think this is big improvement because 
there many users (at least in Russia) who have such troubles with Wine. For 
example user can have correct locale settings (LANG, LANGUAGE and LC_* all 
equals to ru_RU for example) and perfectly working locale-enabled programs 
like cal, nano or date but Wine sometimes cannot work correctly: it display 
Russian letters perfectly, notepad and others has Russian GUI but input of 
Russian letters doesn't work because of famous 
"err:keyboard:X11DRV_ToUnicodeEx Please report: no char for keysym" error 
(sometimes this is becaue user forgot to launch locale-gen but sometimes this 
is because of broken libc - in such case there is no simple solution, only 
recompiling). With this patch Wine works out-of-the-box anyway - that also 
means better integration with X. I found other small improvements as well 
(within source code).
	...And of course + all major improvements listed by Oleh himself.

	My opinion: this patch gives better integration with X+XKB environment and 
probably can be useful for many users. So I think it worth trying...
