The CJK Unified Ideographs Extension B range was introduced with version 3.1 of the Unicode Standard, and provides 42,711 additions to the CJK Unified Ideographs range. The CJK Unified Ideographs Extension B range is located in Plane 2 (the Supplementary Ideographic Plane), which requires the enabling of surrogates in Windows 2000; 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 Code2001 (few), HAN NOM B, MingLiU-ExtB, MingLiU_HKSCS-ExtB, PMingLiU-ExtB, SimSun (Founder Extended) (supplied with Office XP Proofing Tools), Sun-ExtB and Y.OzFontN; 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/.
Users of Internet Explorer 5 for Windows can choose to install updates for viewing Chinese, Japanese and Korean Web pages and to provide an interface and an IME in any of those languages.
Users of Macintosh computers running Mac OS 9 can install Apple Language Kits for Chinese, Japanese and Korean, which include IMEs.
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.
