  Supplementary Ideographic Plane
  
     <text, standard> (SIP) The third plane (plane 2) defined in
     Unicode/ISO 10646, designed to hold all the ideographs
     descended from Chinese writing (mainly found in Vietnamese,
     Korean, Japanese and Chinese) that aren't found in the Basic Multilingual Plane
     .  The BMP was supposed to hold all
     ideographs in modern use; unfortunately, many Chinese dialects
     (like Cantonese and Hong Kong Chinese) were overlooked; to
     write these, characters from the SIP are necessary.  This is
     one reason even non-academic software must support characters
     outside the BMP.
