So section 2.4.2. of RFC 2396

   Because the percent "%" character always has the reserved purpose of
   being the escape indicator, it must be escaped as "%25" in order to
   be used as data within a URI.

is (among other sections) in error, since %25 could be interpreted as
say beeing EBCDIC encoded and thus mean U+000A instead of U+0025?
