Exception when OpenSesame is launched from folder with non-ascii characters

[smathot]

When OpenSesame is launched from a folder with non-ascii characters, the following exception occurs when initializing the osf extension. Somewhere along the lines, a part of the icons path is not properly decoded to Unicode, it seems.

Extension error
