New issue 1972 by [email protected]: Incorrect treatment of unicode
escapes in keywords
http://code.google.com/p/v8/issues/detail?id=1972
The spec is not particularly clear on this, but I gather that unicode
escapes in identifier names are supposed to be decoded _before_
distinguishing between keywords and identifiers. That is,
v\u0061r x = 0
eval("v\\u0061r y = 1")
should parse as valid declarations. That's what FF does, and it's also in
line with other languages like Java. V8 rejects these examples with
SyntaxError. JSC seems to be inconsistent and disallows the first but
accepts the second.
Unfortunately, test262 has no tests for this.
