"4.3.6. Internationalization of Display Strings


The payload MAY provide a standard attribute format that supports
international strings.  This attribute format MUST support encoding
strings in UTF-8 [RFC3629] format.  Any strings sent by the server
intended for display to the user MUST be sent in UTF-8 format and
SHOULD be able to be marked with language information and adapted to
the user's language preference as indicated by RFC 4646 [RFC4646].  
Note that in some cases, such as when transmitting error codes, it 
is acceptable to exchange numeric codes that can be translated by the 
client to support the particular local language.  These numeric codes
are not subject internationalization during transmission. "

   The password authentication exchange MUST support user names and
   passwords in international languages.  It MUST support encoding of

   reference to SASLPrep [RFC4013] or Net-UTF-8 [RFC5198].

   Any strings sent by the server during the password exchange and
intended
   for display to the user MUST be sent in UTF-8 format and SHOULD be
   able to be marked with language information and adapted to the user's
   language preference as indicated by RFC 4646 [RFC4646].  Note that in
some 
   cases, such as when transmitting error codes, it is acceptable to
exchange 
   numeric codes that can be translated by the client to support the 
   particular local language.  These numeric codes are not subject 
   internationalization during transmission. "
