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 BasicMultilingual 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.
