{:?} should not escape printable characters

E.g. äöüß

Currently escape_default is called for every character... I agree that the Debug output shouldn't escape printable characters. Although I think that it should escape C0 and C1 Control Characters. I guess that's what the user wants.
If anyone agrees I will fix that...

I'm on board with this, personally. @alexcrichton, @seanmonstar?

Sounds good to me

Me as well. One can always print as_bytes if they need to compare with
unicode symbols that look alike.
