New issue 2892 by [email protected]: Update identifier syntax to disallow U+2E2F
http://code.google.com/p/v8/issues/detail?id=2892

TC39 discussed http://esdiscuss.org/topic/backwards-compatibility-and-u-2e2f-in-identifier-s and concluded that we should not deviate from Unicode because we don’t want to separate lists from Unicode.

That means `\u2E2F` and `ⸯ` need to throw when used as identifier.

This boils down to updating the script that generates the Unicode tables in `src/unicode.cc` to explicitly blacklist U+2E2F. Unfortunately this script is not open source so I couldn’t write a patch.

For reference, here’s the same issue in SpiderMonkey: https://bugzilla.mozilla.org/show_bug.cgi?id=917436
