Unicode Support in CuteFTP

CuteFTP supports Unicode file names.

  • To conserve Unicode file names, the remote server must support UTF-8 and advertise UTF-8 in its FEAT command.

  • To conserve Unicode file content you must transfer the file using binary transfer mode. (Refer to Specifying Binary or ASCII Mode.)

  • Note that text (ASCII) files transferred in binary mode will retain their carriage return (CR) and line feed (LN) hidden characters, which are not supported by Unix systems by default.

The following areas and features of CuteFTP do not currently support Unicode:

  • Compression: GZIP/TAR files

  • PGP: Key paths and key passwords can include Unicode symbols, but old passwords with Extended ASCII symbols will not work

  • SSL: In the Create Certificate wizard, the following fields cannot include Unicode symbols: Passphrase, Common name, Country, Private key password.

  • SFTP: If you have upgraded to CuteFTP v9 and are using key pairs created with CuteFTP v8, if the password for an existing key contains any Extended ASCII characters, the password will not work. You will have to reenter the password (Tools > Global Options > Security > SSH2 Security) after upgrading to v9.
