How to call a macro, to Convert Accented Characters to Regular, that does not appear in the list?

I am trying to replace accented characters with regular characters.

When I try to run the macro it doesn't appear in the list.

Option Explicit

'-- Add more chars to these 2 string as you want
'-- You may have problem with unicode chars that has code > 255
'-- such as some Vietnamese characters that are outside of ASCII code (0-255)
Const AccChars = "ŠŽšžŸÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðñòóôõöùúûüýÿ"
Const RegChars = "SZszYAAAAAACEEEEIIIIDNOOOOOUUUUYaaaaaaceeeeiiiidnooooouuuuyy"

Sub StripAccent(aRange As Range)
'-- Usage: StripAccent Sheet1.Range("A1:C20")
Dim A As String * 1
Dim B As String * 1
Dim i As Integer

For i = 1 To Len(AccChars)
A = Mid(AccChars, i, 1)
B = Mid(RegChars, i, 1)
aRange.Replace What:=A, _
Replacement:=B, _
LookAt:=xlPart, _
MatchCase:=True
Next

End Sub

Solution

I do not see the option to run the macro in my macros list. The macro name is not appearing in the list to select. I have macros enabled and I have a bunch of others I use so I do not understand why it's not showing. – BvilleBullet 4 mins ago

Please see the comment in the above code.

'-- Usage: StripAccent Sheet1.Range("A1:C20")

You have to call it like this

Option Explicit

'-- Add more chars to these 2 string as you want
'-- You may have problem with unicode chars that has code > 255
'-- such as some Vietnamese characters that are outside of ASCII code (0-255)
Const AccChars = "ŠŽšžŸÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðñòóôõöùúûüýÿ"
Const RegChars = "SZszYAAAAAACEEEEIIIIDNOOOOOUUUUYaaaaaaceeeeiiiidnooooouuuuyy"

'~~> This is how you have to call it. Now You can see the macro "Sample" in the list
Sub Sample()
    StripAccent Sheet1.Range("A1:C20")
End Sub

Sub StripAccent(aRange As Range)
    '-- Usage: StripAccent Sheet1.Range("A1:C20")
    Dim A As String * 1
    Dim B As String * 1
    Dim i As Integer

    For i = 1 To Len(AccChars)
        A = Mid(AccChars, i, 1)
        B = Mid(RegChars, i, 1)
        aRange.Replace What:=A, _
        Replacement:=B, _
        LookAt:=xlPart, _
        MatchCase:=True
    Next
End Sub
