Special Characters - Transfer Fails

As the topic title says, when a filename contains a special character, (Accented or foreign characters) file transfer just fails.
I'm not sure how to solve this, and any help will be appreciated.
Using SmartFTP v4.0.1245.0. Thanks in advence!

Install the latest version. Then post the complete log with the error here.

Thanks for the quick reply.
The thing is, no error is ever returned.
The transfer just gets caught in a "Retry" loop.
The special character is this case is an "×".
Even trying to expand the folder with that character in it doesn't work.
Also, I don't want to rename the files.

The server does not support UTF8. You need to set the correct codepage manually in the favorite properties:
FTP-Transfer page
Code Page option

Awesome! That solved it.
Thanks for the help.
