Yeah, byCodeUnit basically tells Phobos to ignore autodecoding, and 
treats it like the array that it is for the purposes of algorithms and 
ranges. It should provide all the same underlying mechanisms that the 
array provides, including random access, at least that's the purpose.

byChar I think is a conversion routine, meant to be used to shoehorn 
e.g. a wchar[] or dchar[] into a utf8 range. In fact, byChar returns 
byCodeUnit if the types are equal (or at least it should). If it wasn't 
working but byCodeUnit is, please file an issue.
