--- Comment #2 from Dmitry Mikhailov dmikhailov@sypro-nt.ru --- also i have same problem
"wine notepad.exe" works correctly, but "wine sketchup.exe" doesn't print cyrrilic characters. Also doesn't print german umlauts. At the same time cyrrilic characters displays correctly.
while launching "WINEDEBUG=+keyboard wine notepad.exe", on pressing any key in english layout, logging line occurs NtUserToUnicodeEx and KEYBOARD_MapDeadKeysym: while pressing any key with cyrrilic layout - log is idle. while pressing any key with german layout - have similar log lines, as english, except umlauts, on umlauts stderr is idle.
