Fixes #257

I think this is a reasonable alternative to #261

Honestly I prefer the other fix, principle of least astonishment.

My realization that it's just printable ASCII with 0x20..0x3F after 0x40..5F... what possessed them to do this.
(i + 0x20) ^ 0b01100000.

Alright, I've made it more tasteful for my own enjoyment. @resuna :+ )

[skinkie]

And yet another alternative #271 ;-)

Honestly I think you're overthinking this. #261 is the simplest fix.

I honestly don't care as long as one of them gets merged lol.
