not be duplicated exactly in every Chinese dictionary, but which few dictionary compilers can afford to completely ignore. They also serve as the basis for many computer encoding systems, including Unihan. The number of radicals may be reduced in modern practical dictionaries, as some of the more obscure Kangxi radicals do not form any characters that remain in frequent use. Thus, the Oxford Concise English–Chinese Dictionary (), for example, has 188 radicals. The Xinhua Zidian, a pocket-sized character dictionary containing about 13,000 characters, uses 189 radicals, later (10th ed.) increased to 201 to conform to a national standard (see List of Xinhua Zidian radicals). A few dictionaries also introduce new radicals, treating groups of radicals that are used together in many different characters as a kind of radical. For example, Hanyu Da Cidian, the most inclusive available Chinese dictionary (published in 1993) has 23,000 head character entries organised by a novel system of 200 radicals. Table of radicals In Unicode In Unicode version 3.0 (1999), a separate Kangxi Radicals block was introduced which encodes the 214 radicals in sequence, at U+2F00–2FD5. These are specific code points intended to represent the radical qua radical, as opposed to the character consisting of the unaugmented radical; thus, U+2F00 represents radical 1 while U+4E00 represents the character yī meaning "one". In addition, the CJK Radicals Supplement block (2E80–2EFF) was introduced, encoding alternative (often positional) forms taken by Kangxi radicals as they appear within specific characters. For example, ⺁ "CJK RADICAL CLIFF" (U+2E81) is a variant of ⼚ radical 27 (U+2F1A), itself identical in shape to the character consisting of unaugmented radical 27, 厂 "cliff" (U+5382).
