Hi, For now, the vi_VN locale has no special LC_COLLATE rules, while Vietnamese really has special rules: correct order is for instance au àu ân i.e. order depends much upon different kinds of accents. On http://perso.ens-lyon.fr/samuel.thibault/patch-vi_VN you may find a patch to correct this, please apply. Thanks, Samuel Thibault
