Since no semantics has been proposed, then it stands to reason that one
can just assume 1 byte = 1 character and a straight "byte value =
Unicode value" conversion should be adopted, right? (No codepage

Come to think of it, if they're just a generic 32-byte byte array, why
even convert them to strings? They only make sense if they happen to
contain alphanumeric and some symbolic characters (which isn't even a
convention or restriction). Alright, maybe it's useful for displaying to
humans when they just happen to be alphanumeric. Forget I asked.
