C: B282 SEARCH RETURN (SAVE) SINCE 1-Feb-1994
      NOT FROM "Smith"
  S: B282 OK SEARCH completed
  C: B283 SEARCH RETURN (SAVE) CHARSET KOI8-R
      (OR $ 1,3000:3021) TEXT {4}
  C: XXXX
  S: B283 NO [BADCHARSET UTF-8] KOI8-R is not supported
 //After this command, the saved result variable contains
 //no messages.  A client that wants to reissue the B283
 //SEARCH command with another CHARSET would have to reissue
 //the B282 command as well.  One possible workaround for
 //this is to include the desired CHARSET parameter
 //in the earliest SEARCH RETURN (SAVE) command in a
 //sequence of related SEARCH commands, to cause
 //the earliest SEARCH in the sequence to fail.
 //A better approach might be to always use CHARSET UTF-8
 //instead.
