[AccessD] Displaying TAB as [Chr(9)] in a text control

Does anyone know what to do about the little square that appears when using 
TAB (ASCII 9) in a textbox on a report? If I direct the report to a RTF 
document the tab translates perfectly to a TAB as itis supposed to, but it 
will not do it on the report in its natural form. Below is the code Iam 
using in the text control.

="Student No:" & Chr(9) & [StudID] & Chr(13) & Chr(10) & "Course: " & 
Chr(9) & IIf([CourseName] Is Null,[CRICOS_name],[CourseName])
