Translation is done by encoding each character outside the URN
character set as a sequence of one to six octets using UTF-8
encoding [5], and the encoding of each of those octets as "%"
followed by two characters from the <hex> character set above.
the character [%] used in a literal sense MUST be encoded
a character MUST NOT be "%"-encoded if the character is not a
reserved character
SHOULD NOT use [other reserved characters] characters in
unencoded form
each character outside the URN character set [is encoded] as a
sequence of one to six octets using UTF-8 encoding
The presence of an "%" character in an URN MUST be followed by
two characters from the <hex> character set
In addition, octet 0 (0 hex) should NEVER be used, in either
unencoded or %-encoded form."""
