+           characters that are distinguishable from other data within a URI.
+           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."
