There is really no need to escape $symbol; we control this, and it is CGI param safe.

BTW. why use join? The following

        push @result, "$symbol=" . esc_param($params{$name});

would be simplier... we could even use

        $href .= ($i > 0? ";" : "") . "$symbol=" . esc_param($params{$name});

although probably this isn't best idea (worse readibility).
