Details
After bug 694360, a patch landed that made e.g. `var thi\u0073;` a SyntaxError rather than following the compatibility requirements listed here: http://mathias.html5.org/specs/javascript/#escaped-reserved-words
Firefox is the only browser to error on this. It may be correct as per the ECMAScript spec (and in a perfect world, all engines would implement it like this, and no one would use identifiers like that), but it doesn’t match other implementations.
Please consider reverting the change for compatibility/interoperability reasons.
