I can use the base letter A for indexing, it can not be used to identify the actual letter (which may have one or more diacritics floating around). (Sorry you nordic people that I make a diacritic from the ring!) > > An encoding every variant of every character ever written is not?

Your non-unified > approach would require roughly eighteen bits per character. As I understand it each character has only one radical. (I learned that a character consists of a radical plus possibly additional strokes.) You have the misunderstanding that a character is composed of a number of radicals. (BTW, this is true of the Korean Hangul, but that is actually an alphabetic script, each base symbol represents a sound.) > ... > Unique in what sense? Examples? Unique in the sense that they do not contain radicals. (And excuses to you Japanese, Chinese and Korean people for the inaccuracies I wrote.) -- dik t. winter, cwi, kruislaan 413, 1098 sj amsterdam, nederland home: bovenover 215, 1025 jn amsterdam, nederland; e-mail: dik@cwi.nl
