Thanks for the clarification. I should have read the document a bit more carefully. The "extension" described in ISO/IEC TR 14652 seems only to have been the addition of "Eu" for U+20AC EURO SIGN, bringing the total number of symbols to 2330, including private-use assignments and duplicate symbols like "Nb" and "number-sign" and "H-" for U+0023 NUMBER SIGN. Keld is right, though: hex notations like &_U20AD_ can always be used for characters that have no symbol. And Ken is right too: the mnemonic value of short "portable character set" symbols diminishes rapidly anyway. (But look, "K-" is still available for U+20AD KIP SIGN...) -Doug Ewell Fullerton, California
