Notes

Ordre de classement est généralement lexicographique insensible à la casse comparaison selon l'alphabet dans l'environnement local, mais dans certains endroits, des groupes de caractères comparer des unités de classement en simple. Par exemple, «ch» en tchèque suit «h» et précède «i» et «ng» en gallois suit «g» et précède «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".
