IO.cfg file not loading from Notepad ++

Hello, I’m not able to load IO changes I did using Notepad ++, Robotstudio is reporting encoding error requesting ISO 8859-1 encoding. I did this type of encoding but still same error as in link below. Any advice? Thanks in advance.

Maybe the actual error is syntactical and this message is false.

Hallo, you might use ordinary windows-editor. Using notepad++, try to save with charset “UTF8 without BOM”
