Support for UTF-8 encoding is communicated in response to the FEAT command, which occurs after authentication. Therefore, if you provide a Unicode username/password and try to connect to the server via FTP, the connection will fail. EFT starts negotiation in ASCII and can't switch to Unicode until after authentication. If you want EFT to use Unicode from the start, you can change the initial encoding in the interface in the FTP Settings dialog box.
You can specify UTF-8 or Auto-detect encoding for inbound FTP transfers on the Site. For most connecting clients, Auto-detect is preferred and is the default.
To configure FTP encoding
Open the FTP Settings dialog box.
In the Encoding area, click UTF-8 or Auto-detect.
UTF-8—For Unicode-only transfers
Auto-detect—Detects whether to proceed in ASCII mode or can switch to UTF-8 mode for the transmission and receipt of path names and other strings communicated between client and server.
Click OK to close the dialog box.
Click Apply to save the changes on EFT.
