--- Comment #11 from Fábio Capela fabio.capela@yahoo.com 2008-01-19 12:39:41 --- Created an attachment (id=10365) --> (http://bugs.winehq.org/attachment.cgi?id=10365) Hack to make ß key work for bindings in WoW
Just confirmed that the bug exists when using the german keyboard layout and found why.
World of Warcraft uses the result from MapVirtualKeyEx in MAPVK_VK_TO_CHAR mode when binding an action to a key; if the result is 0 (or, apparently, if the result is much larger than 255), it can't bind the key.
The attached patch is an ugly hack to make the ß key work.
