The selector engine doesn't support the HEX escaped characters

[vitallium]

We have:
HTML fragment:

<div id="B&W?"><p>test</p></div>

Selector:

#B\\26 W\\3F

And it doesn't work. Returns 0 elements. Following this document http://www.w3.org/TR/CSS2/syndata.html#characters CSS identifier (or selector) may contain any ISO 10646 character as a numeric code (or HEX code, as I show here).

I have fix for this. If this will be confirmed as an issue.

Confirmed, and I'm not going to lie I am surprised it works in jQuery, but I just confirmed it does. The engine should have no problem matching a selector that includes any ISO10646 character but it definitely does not know try to parse hex codes. That is - it should work using a unicode character just fine, so this should be only a problem in the selector parser.

Looking forward to your code!

Done. Thanks for your work, I look forward to you will contributions in the future!
