...give or take. Some language/script combinations require non-alphabetic characters to represent real words. The people who speak those languages would not call those characters "non-alphabetic". For example, if Unicode required you to have two characters to represent "e with umlaut", and "e" and a "combining umlaut", one can argue ad nauseam whether or not "combining umlaut" was alphabetic. There is not a technical name for "alphabetic and the additional characters you need to form words", nor is there a definitive list. A suggestion would be "word characters, explicitly excluding numerals and symbol characters" (because some people might say that a copyright character is a word character). >I will say that I am (personally, no hats) uneasy importing to the >technical constraints on top level labels what seem to me to be policy >considerations.
