vsftpd and utf8 errors

[xeon]

Hello,

I noticed that on vsftpd 2.0.5 FileZilla client works great however on vsftpd 2.0.6 and later FileZilla client seems to have issue with files/folders with some characters like ½ for example.

I've tested this on other ftp clients and so far FileZilla is the only one not working and giving errors.

I'm thinking this might be related to something in the 2.0.6 changelog for vsftpd:

- Pretend we have proper UTF8 support and respond positively to OPTS UTF8 ON.

Anyway, below is the complete ftp log where I connect open a folder and try to download a file in it.

vsftpd + UTF8 generally works fine. However the files aren't stored with proper filenames in the server's filesystem.

The solution is to delete those files somehow and then reupload them with an UTF-8 capable client such as FileZilla.
