Search and replace text of a certain font

I am trying to write an MS Word 2016 VBA macro that searches for certain text in Courier New font and changes it, using .Find and .Execute. It does not work. For some reason it does not set the .Font.Name property of the search text as specified. Here is the code:

Code:

---

test()
    Dim selRange As Range
    Set selRange = Selection.Range
    With selRange.Find
        .Text = "C"
        .Font.Name = "Courier New"
        Debug.Print "Search text " & .Text & " Font: " & .Font.Name & " Selected text: " & selRange.Text & ", Font: " & selRange.Font.Name
        .Replacement.Text = "G"
        .Execute Replace:=wdReplaceAll
        Debug.Print .Found
    End With
End Sub

---

Here is the text in the word document that I have selected. It is all in Courier New font: A B C

This is the output from the first debug line:
Search text C Font: Selected text: A B C, Font: Courier New

This is the output from the second debug line, indicating that it did not find any matching text:
False

That is strange. I changed the code to Font.NameAscii = "Courier New" and it now works???
