So, my wiki is in French, and that language has 19 additionnal letters. 16 being letters using diacritics, and the last 3 being ligatures.
À -  - Ä - Æ - Ç - É - È - Ê - Ë - & - Î - Ï - Ô - Ö - Œ - Ù - Û - Ü - Ÿ
Those are all letters used in regular words as in the famous sentence:
Dès Noël, où un zéphyr haï me vêt de glaçons würmiens, je dîne d’exquis rôtis de bœuf au kir, à l’aÿ d’âge mûr, &cætera.
In my wiki, in the list of pages or in the category pages, some pages are not sorted properly due to these letters. Examples:
- Gardien des Portes → Glossaire → Gérard
- Mantau Jikam → Maître d'armes
- E pages → F to G pages → I pages → J to Z pages → Échiquier → Île inconnue
In the French alphabetical order, the diacritics are sorted with the regular letter, no matter what (Æ is sorted as AE, Œ as OE and & as ET). Is there a way to change the default sorting system without using DEFAULTSORT for a third of the pages?
