This should be a SyntaxError:
var thi\u0073;
Currently we permit it and actually declare a variable named "this" (although we ban it in strict mode, apparently by accident rather than by design).
See discussion here:

The most persuasive response was Allen Wirfs-Brock's interpretation of ES5:

No one really disagreed.

v1 detect unicode escaped keywords
throws() has a bug: if eval(code) does not throw, the test passes.
