The API docs say "Informally, this set is the set of all characters used as letters of alphabets and ideographs.” Which very strongly implies it is not just ASCII, but covers all Unicode alphabets. Some languages, like Java and Go, can handle non-ASCII letters in identifiers, but most can’t. I would stick with a character set consisting of only upper and lowercase ASCII letters, digits and the underscore. And you’d probably want to force the first character to be a lowercase letter since some languages assign special meaning to identifiers that start with a capital letter or with an underscore. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
