Ahmet Arslan commented on SOLR-9250:
------------------------------------
Yes this one, but you needs to make the chains visible.
It is the <fieldType> tag in schema.
Anyways, the problem looks like your tokenizer breaks/tokenizes your sample
input at the UE char.
Please use analysis admin page to see how your example text is
tokenized/indexed.
Have you read https://wiki.apache.org/solr/MultitermQueryAnalysis ?

> 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*}}).
