Users have been noticing that searching for a word with a special character only returns results with that exact character, when really it should be returning results for that character as well as its English-keyboard equivalent (like Google would). On our beer forum, for example, searching for Kölsch will NOT return results for Kolsch, and vice-versa. Just common sense. I am using Enhanced Search with Elasticsearch, but I believe this behavior is the same with traditional search. If I'm wrong, please move this thread to Enhanced Search Bug Reports.
