Unicode gets unescaped

The obfuscator seems to unescape escaped unicode in strings. For example, consider the following input javascript:

console.log("\ud83d\ude03");
console.log("😃");

Expected Behavior

I expect the unicode escape sequences to be preserved. Something like this is expected:

console['log']('\ud83d\ude03');console['log']('😃');

Current Behavior

Escaped characters are unescaped. For the code above, the default obfuscation options produce:

console['log']('😃');console['log']('😃');

Notice the smiley faces appear as unicode characters, that is, they are no longer escaped. Note that if the "Escape Unicode Sequence" option is enabled then that does not happen and instead we get:

console['\x6c\x6f\x67']('\ud83d\ude03');console['\x6c\x6f\x67']('\ud83d\ude03');

However, from my understanding and documentation, this option is not about unescaping unicode, it is about escaping unicode (or escaping everything in general).
