CJK Unified Ideographs Extension B

U+20000 – U+2A6D6   (131072–173782)

The CJK Unified Ideographs Extension B range was introduced with version 3.1 of the Unicode Standard, and provides 42,711 new ideographs, in addition to those in the CJK Unified Ideographs and CJK Unified Ideographs Extension A ranges. The CJK Unified Ideographs Extension B range is located in Plane 2 (the Supplementary Ideographic Plane). Windows XP and later versions support supplementary characters by default. In Windows 2000, you need to enable support for supplementary characters. These characters cannot easily be displayed in earlier versions of Windows.

The characters that appear in the “Character” columns of the following table depend on the browser that you are using, the fonts installed on your computer, and the browser options you have chosen that determine the fonts used to display particular character sets, encodings or languages.

You can find some or all of the characters in this range in the Windows Unicode fonts BabelStone Han (few), Code2001 (few), HAN NOM B, HanaMin Regular, MingLiU-ExtB, MingLiU_HKSCS-ExtB, PMingLiU-ExtB, SimSun (Founder Extended) (supplied with Office XP Proofing Tools), Sun-ExtB and YOzFontN; and in the Macintosh OS X Unicode fonts Hiragino Kaku Gothic Pro, Hiragino Maru Gothic Pro and Hiragino Mincho Pro.

To see exactly which characters are included in a particular font, you can use a utility such as Andrew West’s BabelMap, or Apple’s Character Palette.

You can try out your browser and fonts with simplified Chinese text at http://www.microsoft.com/China/, with traditional Chinese text at http://www.microsoft.com/Taiwan/ and http://www.apple.com.tw/, with Japanese text at http://www.microsoft.com/japan/ and http://www.apple.co.jp/, and with Korean text at http://www.microsoft.com/Korea/ and http://www.applecomputer.co.kr/.

There are too many characters in this range to display in a single HTML file. You can find a document that displays them all at http://www.unicode.org/charts/PDF/U20000.pdf.
