Alas, even though there's now explicit code page conversion using CP_ACP, part A) = output of Umlauts to a shell terminal is still incorrect: wine: Fehlerhaftes EXE-Format f<?>r Z:\...\rost.ini The <?> is actually an unusual quotation mark box. When I switch gnome-terminal to ISO-8859-15 encoding (LANG is still set to de_DE.UTF-8) then wine displays the correct "für" instead of f?r.
That's the bug 13819.
