Or have two cases of the representation: an array of bytes if every
character is U+00FF or below, or an array of 32-bit words otherwise.

My Kogut compiler does that internally, and makes use of that when
interfacing with C (the default encoding is assumed to preserve ASCII;
if the narrow case has only ASCII chars, a pointer to its internals
is passed to a C function; for this reason it has an otherwise unused
'\0' after the last character).

AFAIK CLISP has 16-bit words as the third case.
