Names are important. I think this discussion would make more progress if Dean's "string" were given another name, like "bytes," and his "view" were named "string" or perhaps "string_view."

That would be a sequence of bytes in a bytes<char>, say.

You'd interpret the bytes<char> with a string<utf_8>, say.

There is no difference, but because "string" connotes "human readable text" to most, using a different name for the raw storage class will dissociate that connotation from the raw storage.
