How to determine ftp server filenames encoding?

Question

I am trying to mount a ftp server with curlftpfc. But the server has unknown encoding, and all the filenames look like ???????.avi, ??????.inf.

I know that I need to specify the encoding for curlftpfc, but what encoding should I use? Is there any simple way to get the encoding used on the server?

Answer 1

Since the filenames are expected to be in russian, the probable encodings include KOI8-R, CP1251 and, more rarely, ISO-8859-5.
