My Excel addin has a feature to remove all line feeds and replace them with a space.

Originally, I had just this (and it worked fine):
Code:
        Globals.ThisAddIn.Application.ScreenUpdating = False
        Globals.ThisAddIn.Application.DisplayAlerts = False
        Globals.ThisAddIn.Application.Selection.replace(What:=vbNewLine, Replacement:=" ")
        Globals.ThisAddIn.Application.Selection.replace(What:=vbCr, Replacement:=" ")
        Globals.ThisAddIn.Application.Selection.replace(What:=vbLf, Replacement:=" ")
        Globals.ThisAddIn.Application.Selection.replace(What:=vbCrLf, Replacement:=" ")
        Globals.ThisAddIn.Application.ScreenUpdating = True
        Globals.ThisAddIn.Application.DisplayAlerts = True
However - I started coming across line feeds that weren't being removed by that code. After playing with it a bit, I ended up getting the ASCII codes for the line feeds I couldn't remove.

I then altered my code to this:
Code:
        Globals.ThisAddIn.Application.ScreenUpdating = False
        Globals.ThisAddIn.Application.DisplayAlerts = False
        Globals.ThisAddIn.Application.Selection.replace(What:=vbNewLine, Replacement:=" ")
        Globals.ThisAddIn.Application.Selection.replace(What:=vbCr, Replacement:=" ")
        Globals.ThisAddIn.Application.Selection.replace(What:=vbLf, Replacement:=" ")
        Globals.ThisAddIn.Application.Selection.replace(What:=vbCrLf, Replacement:=" ")
        Globals.ThisAddIn.Application.Selection.replace(What:=Chr(10), Replacement:=" ")
        Globals.ThisAddIn.Application.Selection.replace(What:=Chr(1), Replacement:=" ")
        Globals.ThisAddIn.Application.Selection.replace(What:=Chr(3), Replacement:=" ")
        Globals.ThisAddIn.Application.Selection.replace(What:=Chr(13), Replacement:=" ")
        Globals.ThisAddIn.Application.ScreenUpdating = True
        Globals.ThisAddIn.Application.DisplayAlerts = True
This works fabulously, however it replaces all 10's, 1's, 3's, and 13's with a space as well...which is bad.

Does anyone know how I can prevent the code from replacing the numbers?
