Escaping of first decimal digits in the current form - is this something what we expect?

[zloirock]

If I understand correctly, with the current spec draft logic, we have:

const string = '40';
const escaped = RegExp.escape(string); // => '\\x40'
const re = new RegExp(escaped); // => /\x40/

re.test('40'); // => false
re.test('@'); // => true

Is this expected behavior?

[zloirock]

It seems it should be something like \x340.

You're right, we should be hex encoding the the digit in this case.

Yes, the intention is to hex encode.
