Mbed CLI cant compile

Mbed CLI

Hi, after sometime my Mbed CLI can’t compile anymore, I have deleted and re installed the program 4 times. Checked Python requirements etc.

Compile output:

Hmm I have a feeling this might be caused by a non-ASCII character in a folder or file name in the code you’re building. If so, it’s definitely a bug.

Thanks for the reply! The problem was with the folder name and the program not recognising nordic special characters (Ä, Ö, Å). After changing folders it worked first try.
