Steps to replicate the issue (include links if applicable):

Open

https://query.wikidata.org/#SELECT%20%3Fitem%20%3FitemLabel%20WHERE%20%7B%20%3Fitem%20rdfs%3Alabel%20%22%D9%82%D9%87%D9%88%D9%87%E2%80%8C%D8%AE%D8%A7%D9%86%D9%87%22%40fa.%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22fa%22.%20%7D%20%7D

What happens?:
"قهوهخانه" returned as the result.

What should have happened instead?:
"قهوه‌خانه" should be returned (for whose don't know the script, see that circle like letter in the middle of the word which should be attached to other letters)

Guess there is some normalization going on that removes whitespaces but ZWNJ shouldn't be removed as is discussed also in https://github.com/w3c/charmod-norm/issues/44

As far I can tell this isn't from the interface as the API shows the issue also,
