SSRS Pass Arabic in Report Builder Query Parameter

Question

I am trying to figure out how my query in report builder can work with source data column nvarchar and arabic text present. If I try to preview the report it says @provider parameter requires a value but it doesn't have one. The data in this column is all arabic. If I test in report build and provider value like منطقة الرياض no results are shown.

SELECT *
FROM [dbo].[CQM_Clinician]
WHERE  @Provider IN ('',[Provider Name])
