The following table shows a map of the actual and proposed allocation on Plane 3, the TIP (Tertiary Ideographic Plane). A description of the presentation conventions used in the table is at the bottom of this page. The TIP (plane 3) is used for CJK Unified Ideographs (unified East Asian ideographs) that are not encoded in the BMP or SIP.
The TIP may also be used for encoding scripts belonging to the Old Hanzi Period, namely those of the Shāng Dynasty, the Western Zhōu Dynasty, the Spring and Autumn Period, the Warring Kingdoms, and the Qín Dynasty. The scripts envisaged for encoding are:
Other CJK related characters, including strokes, radicals, and punctuation are encoded on the BMP and SIP.
(Note: The name "Tertiary Ideographic Plane" has been formally assigned to this plane in Amendment 2 to the 5th ed of 10646.)
