I'm sorry, compose=yes works as expected (I was copy pasting some old
code and forgot about the later improvements in ConTeXt: shame on me).

But the code above doesn't seem to work (I don't get the letter "č"
printed out at all). I would prefer the approach with more fine-tuning
though because "č" is always misaligned. And I seem to remember that
this functionality has been in the core for a long time already, I
just again forgot about it because most fonts include the full charset
