Submit file with forbidden chars in name to WebDAV

[Paco Avila]

There are some forbidden chars in node names (:, [, ], *, \, ", |) How deal
WebDAV with these files? Actually server response is "500 Internal Server
Error" but can I escape the document names (and folder) to clean these
forbidden chars and get a good name? The real question is: where should I
call this escaping method?
