UTF8 support

As far as I can see FlashFXP does not support UTF8 file names at all. This is pretty severe, as a lot of Linux distros default to UTF8 these days. I've tested with proftpd (patched version that sends UTF8 during FEAT), and vsftpd (also patched version that sends UTF8 during FEAT). They both work in FileZilla, but in FlashFXP the double byte characters get corrupted. Example:

09. Jørn Hoel - Next Time I See You.mp3

The two symbols are UTF8 for "ø".

There's a similar topic at the SmartFTP forum:

See rfc:

http://www.faqs.org/rfcs/rfc2640.html

If UTF8 is sent during FEAT the client should ASSUME that names are in UTF8, or try to actually DETECT it. There's code for detection in the rfc. The client may also send OPTS UTF8 ON to explicitly enable UTF8, but as far as I can understand from the rfc this is not required.

Since FlashFXP wasn't designed to handle unicode we're only able to support a small part of the UTF8 character set. Specifically iso-8859-1/Latin-1.

Starting with FlashFXP v3.4.1.1167 I have added support for UTF8 (however it is limited to the iso-8859-1/Latin-1 character set).

Eventually we would like to impliment full unicode support. Though this will most likely require a rewrite.
