Reading UTF32 files

Just a note:
I think all methods that don't take parameters can be called without 
parens, just like you normally use properties, but it's a bit clearer to 
use parens here (because "read" should actually be used as a method).
To take the reference you'd have to use sth like "auto pointer = 
&file.read" ...
