  Ha, ha, ha, ha  <cough>.  4282 is wrong.  And no one implements any of it.

  The MS-CHAP RFCs are silent on the subject of character encoding.  The
unofficial word from Microsoft is "MS-CHAP uses the local encoding".

  Ok... what's that?

  <hysterical laughter>  No one knows.  And there's no way to find out.

  And UTF-8 uses up to 5 octets for a character.  MS-CHAP requires no
more than 2.

  There is *no* way to do the right thing.  You can get close.
Sometimes.  Maybe.  But doing the right thing always?  Impossible.
