Unicode strings in compiled INSERT Queries.

Hi.
Creating INSERT Query using AsInsert with multible values, I pass desired values as array of objects.
I don't want to execute it and my purpose is just to form needed query using SqlKata.
But for string values, instead of N'MyString' I just have 'MyString'. And if it has non-ASCII characters, after executing as EF Core migration operation, I just get ??????? instead of actual value.

Code snippet:

And on of the "entitiy" object fields is string-type value, that passed inside of formed INSERT query incorrectly.
Entity Example:

Any ideas of how to paste string parameters as nvarchar with N, not just 'MyString'?
Feel free ta ask any additional information to figure out the task I'm trying to resolve.
