Item and recipe search doesn't match accented letters when the base character is inserted

In all places in the game that have a search feature (i.e. creative inventory, recipe book and world selection screen), typing a non-accented character in the search box doesn't return matching entries with their corresponding accented letters.

As an example, in Portuguese, the item Lapis Lazuli is translated as Lápis-lazúli. Typing "la" in the search box doesn't show the item, whereas typing "lá" does. Another example is the Spawn Egg in Welsh, translated as Ŵy Geni: the search will only return the spawn eggs if you insert 'ŵ' (with the circumflex), but not 'w'.

Some languages even deliberately suppressed the accents in some words in order to improve accessibility. That was the case of the German translation for Chicken Spawn Egg: Hühner-Spawn-Ei (Chicken Spawn Egg) would not appear in the search if you search for “Huhn” (Chicken), so it was translated as Huhn-Spawn-Ei. The French language had to completely omit the "œ" and "Œ" characters because typing "oe" in the search box wouldn't match them.

This behavior seriously impairs the accessibility and user-friendliness of the search feature. Additionally, it differs from most of the search engines used on the web and in other applications, which would match base characters in the search string with any accented variant of the same character in the elements being searched.
