I'm currently testing the V7 FTP client against various FTP servers for Unicode compatibility. All my testing is using Delphi 2007, the only benefit of Delphi 2009 will be display of non-ANSI characters.
Generally, the OPTS UTF8 or OPTS UTF8 ON command must be sent before most servers support UTF8 file listings or uploads, and even then it may not include Unicode characters outside the ANSI codeset. I've tested four common FTP servers detailed below for UTF8 support, if anyone is using any other common servers, please let me know so I can test them. Microsoft IIS/5 and IIS/6 no UTF8 support, IIS/7 FTP for Windows 2008 was released March 2008 and finally supports SSL and UTF8, not yet tested. ICS V6/V7 - does not support UTF8, yet, due real soon FileZilla Server - fully Unicode capable, defaults to UTF8 ON returning UFT8 file listings and uploads, but can be disabled with OPTS UTF8 OFF command when listings revert to ANSI. WS_FTP Server 6.1.1 - fully Unicode capable, defaults to UTF8 OFF and returns ANSI file listings, OPTS UTF8 or OPTS UTF8 ON enables UTF8 file listings and uploads, UTF8 can not be set off so don't send command if ANSI needed MLST fails with 501 if file name includes a space RhinoSoft Serv-U FTP Server v7.2 - no Unicode support, defaults to UTF8 OFF but returns UTF8 file listings (with ? for non-supported unicode characters), OPTS UTF8 ON enables UTF8 uploads. OPTS UTF8 OFF command reverts listings to ANSI MLST fails with 550 for file names with any unicode escaped characters MDTM YYYYMMDDHHMMSS seems to fail for all files, maybe only those not in root directory (MDTM used to work in earlier releases) Gene6 FTP Server v3.10.0 - fully Unicode capable, defaults to UTF8 OFF and returns ANSI file listings, OPTS UTF8 or OPTS UTF8 ON enables UTF8 file listings and uploads, UTF8 can not be set off so don't send command if ANSI needed.
