My understanding is that if you're setting charset=utf-8 in either the
server response, or the (x)html head section, the browser should only
allow utf8 in form fields.

If you're doing that, this shouldn't be necessary, but you can also
set it in the form's attributes:

    ---
    attrs:
      accept-charset: UTF-8

I'm not sure under what circumstances Filter::Encode should be
necessary - I've never used it.
My best advice would be to read HTML::FormFu::Manual::Unicode
