Even on plain WINEPREFIX I am unable to get Polish-specific chars to work. On unix (Arch x64) everytching works fine. Wine is setting wrong codepage in registry ( in HKEY_CURRENT_USER\Software\Wine\Fonts\Codepages apears "1252,437" while it should be "1252,437") Code: $ locale LANG=pl_PL.utf8 LC_CTYPE="pl_PL.utf8" LC_NUMERIC="pl_PL.utf8" LC_TIME="pl_PL.utf8" LC_COLLATE="pl_PL.utf8" LC_MONETARY="pl_PL.utf8" LC_MESSAGES="pl_PL.utf8" LC_PAPER="pl_PL.utf8" LC_NAME="pl_PL.utf8" LC_ADDRESS="pl_PL.utf8" LC_TELEPHONE="pl_PL.utf8" LC_MEASUREMENT="pl_PL.utf8" LC_IDENTIFICATION="pl_PL.utf8" LC_ALL= Running Code: $ LC_ALL=pl_PL wine notepad.exe -- or -- $ export LC_ALL=pl_PL $ export LANG=pl_PL $ wine notepad.exe doesn't do the job. Both on wine wine-1.1.43 and wine-1.2_rc2-1 Help me pleas :)
