6852                    Note that the forward slash character ('/') has a special meaning in
6853                    filename / path based arguments: it acts as separator of the nodes in
6854                    the path, thus if a directory- or filename includes a forward slash
6855                    (not intended as path node separator), you MUST escape that slash
6856                    either with the respective hex escape sequence ("\x2f") or with the
