The RFC 3986, warns about these "[","]" characters, but leaves it up to the implementor. Firefox, IE and Safari browsers support these characters. http://tools.ietf.org/html/rfc3986
"Special care should be taken when the URI path interpretation process involves the use of a back-end file system or related system functions. File systems typically assign an operational meaning to special characters, such as the "/", "\", ":", "[", and "]" characters, and to special device names like ".", "..", "...", "aux", "lpt", etc. In some cases, merely testing for the existence of such a name will cause the operating system to pause or invoke unrelated system calls, leading to significant security concerns regarding denial of service and unintended data transfer. " The now, obsolete http://www.ietf.org/rfc/rfc2396.txt, had them listed as unwise characters " Other characters are excluded because gateways and other transport agents are known to sometimes modify such characters, or they are used as delimiters. unwise = "{" | "}" | "|" | "\" | "^" | "[" | "]" | "`" Data corresponding to excluded characters must be escaped in order to be properly represented within a URI.
