------- Additional Comments From dmitry@codeweavers.com 2007-10-07 23:16 ------- Wine sets its internal locale based on the locale settings in the underlying system. So, if your locale is not set to chinese this bug is invalid.
Try for intance running your app using command line below:
LANG=zh_CN wine program.exe
