Fun fact, ch is a single letter in Czech, except when it is not, which sometimes happens with some composite words. This means you cannot correctly determine lexicographic ordering without a dictionary.

Ch is an illusion made by big spřežky to sell more pseudoalphabet
@ozzelot @poni ch should not be single letter and I think we should use the new law about general referendum to vote about it and codify it.
