Characters are replaced by a diamond with a question mark

[Allan_Zimmermann]

I kind of agree with @AndrewK this sounds a lot like a culture issue, mostly due to you mentioning it happens in other places besides invoke code too.
At first i though about this one

Invoke python code saved turn Chinese characters to unreadable square

It happened when saving the code some line with Chinese characters got saved with unreadable square, and cause error when running as: [image] the line should tried to read from directory : “Z:\PAIT\WACA\出貨明細規格編號對照表.xlsx” sometime the error appeared within dictionary value within a double quotes.

i never found the time to test this, so don’t know what was the issue there.
