disallow quantifiable anchors in unicode mode #135

Closed JLHwung closed 10 months ago

Fixes #134

/cc @mathiasbynens @nicolo-ribaudo

It seems to me that the spec does not disallow quantified +/- lookahead in unicode sets mode, as is in unicode mode:

https://tc39.es/ecma262/#prod-annexB-Assertion

But both JSC and V8 disallow such productions. It seems to me an oversight in the spec.

In unicode sets mode, the UnicodeMode flag is enabled: https://tc39.es/ecma262/#sec-parsepattern
