Is this really corruption or is it due to the file having been written using the wrong language settings or UTF settings?

A lot of Linux systems have the iconv command to convert from one NLS setting to another.

Usually "corruption" via ftp or sftp transfer is a seldom thing. Can you get a checksum of a corrupted file, then a checksum on the remote source file to verify that transfer did not corrupt.

If you want a script it would be a one-time deal, because corruption due to file transfers does not cause the same screw-ups in the data time after time. Because of that, scripting is not a great solution. If you have enough virtual memory, the Linux vim editor or an editor on a Windows desktop like Ultraedit is a better choice.

If you are getting the same kind of corruption it is very likely the garbage you see was already in the file before you got it, because of a programming error in the code that created the file, like buffer overflow. Consider fixing the root cause.

And. Yeah, I know -- the people on the creation side of things will fight the idea. But that is politics not computing.
