UTF-8 support for FTP-Servers

Filenames encoded with UTF-8 encoding must be processed correctly.

This affects the processing of german "umalute" in file-names.

New Options to activate UTF-8:

objOptions.PreFtpCommands.Value("OPTS UTF8 ON");
objOptions.ControlEncoding.Value("UTF-8");

If the FTP-Server does not support UTF-8 but filenames contans utf-8 coded characters the option "PreFtpCommands" has to be used as shown in the above example. Default is "".

With the Option "ControlEncoding" the Client will activate the utf-8 feature. Default is "off".

An example for using this options in an ini-file :

[transfer-example]
...
control_encoding=UTF-8
preFTPCommand=OPTS UTF8 ON
...

see SOSFTP-75 for Option PreFtpCommands.
