--- Comment #4 from Alexandre Julliard julliard@winehq.org 2010-07-13 08:21:07 --- Desktop files are specified to be in UTF-8, though strictly speaking non-ASCII chars are not allowed in the Exec key. It does say that expanded field codes need to be converted to the proper locale, and I'd argue that KDE should be recoding the command line the same way, even if that's technically not required by the spec.
