Hi. I have installed OpenFoam. However the error of Blockmesh component appears in all the example files when I open them. The error message is: **1. Solution exception:‘ascii’ codec can’t encode character ‘\u59DA’ in position 106**. And other example files are the same.

Traceback:  
Runtime error (EncoderFallbackException): ‘ascii’ codec can’t encode character ‘\u59DA’ in position 106

Traceback:

Just a guess: This might be caused by running a non-English Windows.

Thanks! You are right. The file path contains non-English words. I have created a new Microsoft account and now it works well.
