Hi!

I'm getting a freeze in Addon Manager with v0.19_pre, if I select a workbench that has already been installed in the GUI. It seems that the conversion from unicode to ascii causes a problem:

The Addon Manager stops receiving any user commands, but it's possible to close the frozen Addon Manager window using the "x" in top right corner, after which FreeCAD itself continues to work normally. I have Python 2.7 and Qt 4.8, could it be that one of those is too old and chokes at unicode characters? It seems that the green highlighting somehow chokes the parser.

Yes, pretty much it's a Python 2 vs. Python 3 thing. I think most developers aren't checking compatibility with Python 2 because it's already end of life, so I think we really should push everybody to migrate to Py3/Qt5.
