Issue with requests containing unicode characters


I got list of entities stored in DB, one of entity attribute is unicode string.
When I trying to retrieve one with certain unicode characters, like:

let words =
  realm.objects('Word').filtered('str CONTAINS $0', unicodeSequence)

I get empty array.
Although I know that it should contain entities in it (as I have used Realm Browser and verified that my DB contains entities that should match my request).

Is any additional setup required?
What is the reason for that?


String matching is limited to Latin Basic, Latin Supplement, Latin Extended A, and Latin Extended B (UTF-8 range 0–591). We should add it to our JavaScript documentation like our documentation for the Android and iOS products:


Thank you! I am working with React-Native and haven’t found this restriction on the corresponding docs.
Is there any workaround to be able to use unicode characters?
