Inserting a graphic into a text line at a bookmark

I have a Purchase Order Access form that generates a Word Document with the
desired content.  On the PO form there are several checkboxes that indicate
flags to be placed on the purchase order
.
I use the following code in the process.

-----------
With objWord.ActiveDocument.Bookmarks

   If bolMTR Then .item("mtr").Range.Text = Chr(129) & "   Certified Mill
Test Reports Required (2 copies)"
   If bolMSDS Then .item("msds").Range.Text = Chr(129) & "   Material
Safety Data Sheets Required (2 copies)"
   If bolCOC Then .item("coc").Range.Text = Chr(129) & "   Certificate of
Compliance (2 copies)"
-------------

the Chr(129) prints an empty checkbox.  I would like it to print a checked
checkbox.

I guess I can do that
    by changing the font and printing a wingding character
    inserting a small graphic into that line of the word document

Unfurtunely I can't figure out how do do either.  Anybody have any hints.
