Mystery Special Character appearing in files.

[John R Ownby-Hibner]

I’m working with a file that keeps getting a ‘special character’ added and messing up the file import. It appears as US. I’m completely confused and can figure out what it is.

Hello John-R-Ownby-Hibner,

what do you mean by

keeps getting a ‘special character’ added

?
Does it mean while editing the file you suddenly have those chars listed?
Can you check which encoding is used when editing the file?
Which npp version and operating system do you use?
Where does this file come from? Different os like Linux, Mac, …

Can you make a screenshot and upload it to imgur or similar hosters?
imgur, no registration required.

Cheers
