FTP: unsupported path

File modules/access/ftp.c contain block:

if( p_sys->url.psz_path &&
        (p_sys->features.b_unicode ? IsUTF8 : IsASCII)(p_sys->url.psz_path) == NULL )
    {
        msg_Err( p_access, "unsupported path: \"%s\"", p_sys->url.psz_path );
        goto error;
    }

FTP server can use UTF-8 encoding, but don't show it (FEAT command)! FTP server can use any encoding, for example Windows-1252!

I recommend simply removing this block of code.
