Notas

Ordem de comparação é tipicamente comparação de maiúsculas e minúsculas lexicográfica de acordo com o alfabeto local, mas em algumas localidades, grupos de personagens comparar unidades de agrupamento como individuais. Por exemplo, "ch" em checo segue "h" e precede "i", e "ng" em galês segue "g" e precede "h".

Original:

Collation order is typically lexicographic case-insensitive comparison according to the locale's alphabet, but in some locales, groups of characters compare as single collation units. For example, "ch" in Czech follows "h" and precedes "i", and "ng" in Welsh follows "g" and precedes "h".
