Re: Rebinding international characters

[Richard Stallman]

    However, I wonder: the manual (and AFIR the FAQ as well) suggest to
    use a unibyte code, as in `[241]', to bind non-ASCII keys, saying it
    works in more cases.  If this is no longer true, i.e. if using the
    character itself, as in `?x', is a better (or the only) way, we should
    fix the docs.

What cases does each of them now work in?
