To enable the unicode feature, you may need to do the following steps:
1. Make sure you are using the FTP client Unicode version.
2. Make sure your OS is Windows NT/2k/XP/2003/Vista.
3. Make sure the server supports Unicode/UTF-8 charset, as we know RaidenFTPD and G6FTPD has this feature.
4. Make sure the font of "remote/local/queue" is unicode font, "tahoma" is recommended, to set this option, press F6 in the client main window, and click the "Font" node at left side.
