@tsaniel Damn, I thought I'm the first one who worked that out.
Just got the crazy constructor thing working to get the latest missing chars:

m = (0..constructor+"")[11]

But the tools seems to be broken in Node and Chrome.

Array.prototype.sort called on null or undefined

I guess that's an issue when they try to get "w" using this:

[].sort.call()

In old browsers it returned window but now it doesn't.

Ps: The source of this converter is a bit more readable:
