Okay, now it's time for me to slow down. Now I've come a full circle
back to reducing bytes_to_utf8() to being again equal to just turning
on the UTF-8 flag :-) So if we limit bytes_to_utf8() to operate only
on 0..127, the bytes_to_utf8() becomes redundant.

This is still valid since the utf8 might be coming from somewhere
else than bytes_to_utf8() (assuming the above silly bytes_to_utf8()).
