How to store and read data in SQL Server without font formatting in C#?

Question

The users are entering data in different fonts(most probably by copy-pasting data with fonts) but I want to store them as regular data. My column type is nvarchar.

The data appears like this:

 
ᴩᴀᴅᴍᴀᴍᴍᴀ ᴛ

And if I query on ColumnName == "", it return these with empty strings.

How can I save them and read them as normal SQL text?

Steps to reproduce : Insert some text having font to a nvarchar column.

C_User user;
user = new C_User
{
    Name = input.FirstName + (string.IsNullOrEmpty(input.LastName) ? "" : " " + input.LastName),
    EntityType = typeof(C_Patient).Name
};
context.C_User.Add(user);
