Additional Information:
Brave is not Recognizing German Umlauts like ä ü. Brave Replaces it with russian symbols. The screenshot i attached is from the Wikipedia searchbar. tried everything, upgrading brave, clearing everything and resetting brave, disabling shields and removing all addons. In other Browsers this is not a Problem and every umlaut gets recognised like it should, but somehow in brave its not the case.
