Typically, if I'm building a URI within Catalyst, I'll use
$c->uri_for( $action, \%query )
otherwise, I'll use URI.pm's $uri->query_form( \%query )

That should take care of encoding.

To build the %query hash, if you don't need to worry about validating it,
I'd not bother with formfu at all, and just use either
    $c->request->parameters() under Catalyst
or $query->Vars() with a CGI.pm-compatible query.

If you do need to run the data through formfu first, then it's worth
taking some care
in case some parameters were nested, so you'll need to flatten it out again.
Something like this should work.

my %query;

for my $name ( $form->valid ) {
    $query{ $name } = $form->param( $name );
}

If any fields may have multiple values, I'd suggest you test that
uri_for() or query_form()
(whichever you use), can handle arrayrefs of values correctly.

Hope that helps,
Carl
