           URIs that differ in the replacement of a reserved character with its
           corresponding percent-encoded octet are not equivalent.  Percent-
           encoding a reserved character, or decoding a percent-encoded octet
           that corresponds to a reserved character, will change how the URI is
           interpreted by most applications.  Thus, characters in the reserved
           set are protected from normalization and are therefore safe to be
           used by scheme-specific and producer-specific algorithms for
           delimiting data subcomponents within a URI."
