It should be useful if Logseq’s search is able to ignore diacritics. Even for linking a page.
So if I search for “Espana” I can get “España” as result. And be able to link [[Espana]] to an España page.
Another examples:
[[Cigüeña en el camión]] -> “Ciguena en el camion”
[[El càrrec que ara té]] -> “el carrec que ara te”
Equivalence of other characters like (for example): ç -> c, ß -> b should be ideal.
