[Alain] There is no penalty, you can have as many groups as you want. Do
not make a confusion with PC implementations which are limited to 3 levels
in only one group, and where no group 2 is implemented.
On the Canadian keyboard, typical upper and lower case French letters
are available in group 1, but Scandinavian upper and lower case letters are
available in group 2. (and in fact the French ligatures OE too). There is
no penalty. Easy.
