You are right that Bison wants at least to be able to read
the ASCII part of the 8 bits, so that sort-of means UTF-8,
if we consider that Latin 1 and the like are dead.

If we were to ignore the BOM, then at least we should check
that they match UTF-8, and reject the file otherwise?

FWIW, the D compilers for instance obey these BOM, including for
other codings than UTF-8.
