* regexp search: The search itself can be implemented bytewise, exactly
as if it was a fixed-width encoding. Compiling the regexp can
_almost_ be implemented as if the UTF-8-encoded regexp was in a
fixed-width encoding, with just one added complication: a multibyte
character followed by `*', `?' etc, must be compiled in such a way
that the suffix operator applies to the whole character, and not just
its final byte. (In practice, it's probably more straightforward to
handling compiling somewhat differently than outlined here, but you
get the idea).
In unibyte land, "." matches a byte. OK.
In multibyte land done "bytewise", "." matches ____________.
(What goes in the blank?)
