Essentially, in Slovak it is impossible to implement algorithmical alphabetical sorting without understanding the language, to determine whether "ch" appears on the word stem boundary. But yeah, you can sort 99.99% of words by assuming it does not... and maybe increase it to 99.9999% by making an exception for words starting with "viac-".
