Set FTP Command and Directory-Listing Charsets

Demonstrates the CommandCharset and DirListingCharset properties, which control how non-ASCII text is encoded in commands (including remote paths and filenames) and how directory-listing responses are decoded.

Background: FTP predates Unicode, so servers vary in how they encode filenames; getting non-ASCII names right means matching the server's encoding on both sides. CommandCharset (default ANSI) governs outgoing paths and filenames, while DirListingCharset governs decoding of LIST/NLST/MLSD replies. Modern servers typically use UTF-8 — often negotiated automatically via OPTS UTF8 ON — but setting these explicitly resolves mojibake with servers that do not advertise it.

// CommandCharset is the encoding used for commands containing non-ASCII text, including remote
// paths and filenames.  The default is ANSI; set utf-8 when the server uses UTF-8 filenames.

// does not affect commands or paths.
