I know the solution with active characters, of course. But this implies
many problems (\uppercase, \lccodes, letters in csnames etc.) thus we
never used active characters for Czech/Slovak in our csplain format.
Luatex strictly requires UTF8 encoding on the input thus I mean that
there exist some posibilities to control the conversion from this input to
the TeX internal encoding.
