I think about the best we can do is something along the lines of:

sv2cstr()
{
... if (Perl_vverify(sv))  return utf_u2e(SvPV(sv));
...
}

I dont the the utf_u2e is strictly needed (other than that it strdups)
as I don't think versions can have utf8 chars, or at least that $^V
will not have utf8 chars (and even if it did it would only cause
problems if they had codepoints in >128  <255).

We would still have issues with typeglobs...
