turn non-breaking hyphens, smart quotes etc into equivalent ascii characters

Last Modified: 2012-05-10

My routine saves a document to a windows file system.  The name of file comes from the cells(1,1)

I use the attached function to clean cell(1,1) by dropping colons, slashes and other invalid characters.  

sometimes the cell contains smartquotes  like a non-breaking hyphen. My routine is dropping those characters, when I would prefer to treat them as their ascii equivalent of '-', single quote etc

I know how to do it with a series of vba lines like

str = substitute(str, chr$(150),"-")
str = substitute(str, chr$(151),"-")
etc repeat for non-breaking space, left leaning single quote, right leaning single quote etc

But, I was wondering if there is a way of doing the same thing in regular expressions??

Function func(cell As Range)
  ' set reference to microsoft vbscript regular expressions 5.5
    Dim reg As New RegExp
    Dim test As String
    Dim matches As MatchCollection
    Dim m As Match
    test = cell.Value
    With reg
        .Pattern = "[^\w~!@#$%^&()_+{}`\-=[\];',.]+"
        .Global = True
        Dim ans As String
        func = reg.Replace(test, " ")
    End With

End Function
