The generic URI syntax mandates that new URI schemes that provide for
the representation of character data in a URI must, in effect,
represent characters from the unreserved set without translation, and
**should convert all other characters to bytes according to UTF-8, and
then percent-encode those values**. This requirement was introduced in
January 2005 with the publication of RFC 3986. URI schemes introduced
before this date are not affected.[1]
