The following query gives an empty result on Wikidata, but it should return one match:

PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX ql: <http://qlever.cs.uni-freiburg.de/builtin-functions/>
SELECT * WHERE {
  wd:Q40 @de@rdfs:label ?austria_label_de .
  [ ql:contains-entity ?austria_label_de ; ql:contains-word "Öster*" ]  
}

I doubt that this has anything to do with umlauts, the same issue seems to occur when doing this with germany wd:Q183 accordingly.
