Non unicode Font Error when Insert data into the table ?

I have used VB6 textbox font non unicode and SQL Server 2005 express connection insert data into the table fails Font non unicode (font 1byte) ? only a few words eg: TextBox.Text = "Nguyễn Thị Nỡ" as recorded in Table = "NguyÔn Th~ N´". ask anyone encountered this situation and how to fix it.

"INSERT INTO SINHVIEN VALUES ('0001','10CT','Nguyễn Thị Nỡ','12/04/1991','TP.HCM','Male','CNTT')"

Are you using the same font to view the data?

I has had error save database but i has had view normal

I have no idea what that means nor how it was meant to answer the question
