VBA Pattern Fail When Totally Obvious

When I ctrl-f in a spreadsheet, I can find the text, "child Support," but when I'm using it as a pattern it fails. Other obvious words work, like "Date," for instance.

This spreadsheet was converted from a PDF. Could there be some hidden null characters that are causing this column to be ignored?

Private Function RegExTest(s As String) As String
    Dim re, match
    Set re = CreateObject("vbscript.regexp")
    re.Pattern = "(child support)"
    re.Global = True

    For Each match In re.Execute(s)
        MsgBox match.value
        RegExDate = match.value
        Exit For
    Next
    Set re = Nothing
End Function

(Apologies if this code is rough, I'm a contractor and the box I'm really on is nannied by some bs so I can't copy and paste.)
