Read and write utf8 string in microsoft local database

Question

I am writing a WindowsForm application. I am using Visual Studio local database. Every thing is OK, but if I write some UTF8 content in forms, after saving and getting the content again it shows in this form "????". I think there is problem with database, but I don't know how to configure database to store utf8 content.

Answer 1

The field in the database needs to be an nvarchar instead of a varchar.
