Currently, search does not return results unless you pick the exact right character.
For example, if you're filtering for First Name > Contains "Helen," you will get no results for "Hélène."
Conversely, if you search for "Zoé" but the user entered an anglicized spelling like "Zoe," you will also get no results.
This makes supporting a bilingual audience more challenging. If our filters can have slightly more fuzziness when looking for strings so that this isn't the case, it would make supporting users much quicker and more efficient.
