item sorting order umlaut issue (german locale)

[acbugreport]

Describe the bug when doing an import, the website puts umlaut letters after z in the sorting order, while the game treats them as being the same letter without umlaut.

Expected behavior identical sorting order as ingame

Additional context

Example:

sort order website (german):

Laborbrille Lagenshirt Lagentop Lamellenbrille Landstreicher-Outfit Lauf-Shorts Leinenumhängetasche Lumpenhose Lumpenhut Lumpenkleid Längsstreifenhemd Läuferleggings Löcherpulli

sort order ingame: Laborbrille Lagenshirt Lagentop Lamellenbrille Landstreicher-Outfit Längsstreifenhemd Läuferleggings Lauf-Shorts Leinenumhängetasche Löcherpulli Lumpenhose Lumpenhut Lumpenkleid

so for the sorting order, Nintendo goes with a for ä, u for ü, o for ö and ss for ß

it's a minor issue, but can involve quite some scrolling when importing a large list by text...
