New issue 1958 by [email protected]: `SyntaxError: Unexpected token ILLEGAL` when using a valid JavaScript identifiers 
http://code.google.com/p/v8/issues/detail?id=1958
According to http://es5.github.com/x7.html#x7.6 (spec), http://mathiasbynens.be/notes/javascript-identifiers (summary), and http://mothereff.in/js-variables#a%5Cu200d (validator), `a\u200d` is a valid JavaScript identifier. 

However, JavaScriptCore doesn’t seem to support it:

    var a\u200d; // throws SyntaxError: Unexpected token ILLEGAL

I believe this is a spec violation.
