I don't know what it should do (ftplib needs to worry about that).

There is no ftplib there. FTP server is ProFTPd, ftp clients of all sort, one, e.g., an ftp client built-in into an automatic web-camera. I use python programs to process files after they have been uploaded. The programs access FTP directory as a part of local filesystem.

I do know what it shouldn't do, however: it sould not return a utf-8b string which, when used to create a file, will create a file reproducing the byte sequence of the remote machine; that's wrong.

That certainly wrong. But at least the approach allows python programs to list all files in a directory - currently AFAIU os.listdir() silently skips undecodeable filenames. And after a program gets all files it can process it further - it can cleanup filenames (base64-encode them, e.g.), but at least it can do something, where currently it cannot.

PS. It seems I started to argue for the PEP. Well, well...

Oleg.

       Programmers don't die, they just GOSUB without RETURN.
