Is it normal that the IronPython tests fail? Seems that some LOG file is missing.

Hi @jorgepiloto and @SMoraisAnsys ,

I was able to reproduce the issue, and we need to add the encoding line at the beginning of the file (before the license header), for instance in aedt_logger.py:

I found the issue because the .log locally told me :)

This modification is only needed for the files where # -- coding: utf-8 -- is defined... @jorgepiloto could you make the changes?

Thanks!

Hi @Samuelopez-ansys, thank's for pointing this out. Let me fix this. I hope the ansys-license-headers hooks does not remove those UTF8 lines.

[jorgepiloto]

Changing this to draft. Pinging @klmcadams.

The license headers get placed on top of the # -*- coding: utf-8 -*- line. This makes Python to ignore the actual encoding.

Adding a custom template leads to a duplicated # -*- coding: utf-8 -*-:

# -*- coding: utf-8 -*-
... LICENSE STUFF ...

# -*- coding: utf-8 -*- (the original one)

@jorgepiloto Could we merge this PR?

[jorgepiloto]

I crafted a custom template to ensure the UTF-8 line is added before every license check. Before adding the headers, I removed every UTF-8 line using a custom script.

Everything should be ready to go now.
