Description

While testing UTF-8 character searches, which worked, we have noticed a combination that fails. Testing with the data Tùûüÿ€àâæçéèêëïîôœm, we found the search worked, but by adding a wild-card (e.g. Tùûüÿ€àâæçéèêëïîôœm*), the search fails. Adding the wildcard before the € symbol worked (i.e. Tùûüÿ*).
