Have a look at it: http://www.open-std.org/JTC1/SC22/wg14/www/docs/n1124.pdf ９, code point 0xff19, is not in that list. The maximum one is 0xd7a3, in fact. This is not a bug, this is an enhancement. However, rather than an arbitrary and frozen list, I /would/ prefer basing it simply on Unicode properties, such as Java's choice: identifiers may start with letters or numeric letters, and may contain, in addition to those, connecting punctuation, decimal digits, and combining and non-spacing marks. In other words: Identifiers may start with code points from the general categories Ll, Lm, Lo, Lt, Lu, Nl. Identifiers may contain code points from the general categories Ll, Lm, Lo, Lt, Lu, Mc, Mn, Nd, Nl, No, Pc. Java also allows Cc and Cf, of whose usefulness I'm not so convinced. These are control characters and things like "soft hyphen", which isn't even supposed to be displayed unless the word line-wraps. Too much potential for confusion IMHO. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
