>and I wouldn't know how that affects everyday life.

It mostly affected lexicographic order. 'ch' was between 'c' and 'd'.

So for example, when 'ch' was a separate letter in the alphabet, 'chico' (little, boy) would come after 'cristal' (crystal) in the dictionary. Now it's the other way round.

Something similar happened with 'll'.
