Thanks for the file. That fixed the problem :)

OK, so it's about filenames, NOT file contents. You didn't specify protocol.
Anyway, did you read this?

I have also sent you an email with a dev version of WinSCP to address you have used to register on this forum.

My WINSCP is 5.5.4 Build 443, and yes the problems is the content in the external site.

What version of WinSCP are you using? What protocol? Is this about file names or file contents in an internal editor?

My WINSCP works fine, but I have problems reading scandinavian letters on extern site (no problems in local site).
Are there any adjustment to set for reading æ ø and å ?
