With Word, can VBA identify chr(160) as an unbreakable space, different from chr(32), a normal space?

I am working with VBA in Word to analyze all the words in a given document and I want it to recognize numbers written as strings. My goal is to get the program to recognize that not only are "21" and  "twenty-one" numbers, but "vingt et un" and "ein und zwanzig" are numbers too. The program solves that by putting in unbreakable spaces to make such multi-word numbers single units that the program recognizes.
     My problem is that if I save the revised document so that I will not have to add those spaces the next time I run my program on the text, the program cannot see that "vingt@et@un" (where @ is an unbreakable space) is different from "vingt et un".  
     I do not want to change the spaces to some other character, because I want the document to look the same as it did before the program added the unbreakable spaces.
     I suspect the problem is unsolvable. Any suggestions to the contrary are most welcome.

Sorry, it should be

That is exactly what I wanted. Thanks.
     If it is of any interest to see how I implemented the solution, here is the code I used. Note that z() is a string array holding a series of expressions that have what should be unbreakable spaces. The "With Selection" and "With Find" are not closed since I need them for subsequent lines of code:
With Selection
            x = "vingt et un|trente et un|quarante et un|cinquante et un|ein und |zwei und |drei und |vier und und |fünf und |sechs und |sieben und |acht und |neun und |"
            x = x & "treinta y |cuarenta y |cincuenta y |sesenta y |setenta y |ochenta y |noventa y"
            z() = Split(x, "|")

            With .Find
                  .Forward = True
                  .MatchCase = False
                  For i = 0 To UBound(z)
                        Selection.HomeKey Unit:=wdStory
                        .Text = z(i)
                              If .Found Then
                                    If InStr(Selection, Chr(160)) = 0 Then
                                          .Text = " "
                                          .Replacement.Text = "^s"
                                          .Execute Replace:=wdReplaceAll
                                          .Text = z(i)
                                    End If
                              End If
                              If .Found = True Then
                                    Selection.Collapse wdCollapseEnd
                              End If
                        Loop While .Found
                  Next i
