[pogojens]

Hey :)

I found a Problem: when I'm trying to save some of my layouts i recieve a error Message.

Does somebody has any ideas?

EDIT: found the Problem and a workaround - it has to do with öäü character. It is not possible to use them in footprints and even not in comments. The Workaround is not to use them ;-)
greetings, Jens

Thanks for diagnosing it. I'd still rather make this work so that the plugin can handle what KiCad can handle. Can you prepare and attach a test project.

If I'll not be able to fix it, I'll at least generate meaningful error message.

@pogojens ping. If you have the time and will could you test the plugin again for this issue as it should be solved now?
