You can replace forbidden chars by another :)
Public Function OnlyChars(ByVal txt As String, ByVal Uchars As Boolean, ByVal Lchars As Boolean, ByVal Digits As Boolean, Optional Remplacement As String) As String
Dim h As Long
Dim tempon As String
For h = 1 To Len(txt)
num = Asc(Mid$(txt, h, 1))
'suppression des uchars
If Uchars Then
If num >= 65 And num <= 90 Then
tempon = tempon & Mid$(txt, h, 1)
Else
tempon = tempon & Remplacement
End If
End If
If Lchars Then
If num >= 97 And num <= 122 Then
tempon = tempon & Mid$(txt, h, 1)
Else
tempon = tempon & Remplacement
End If
End If
If Digits Then
If num >= 48 And num <= 57 Then
tempon = tempon & Mid$(txt, h, 1)
Else
tempon = tempon & Remplacement
End If
End If
'If Uchars And Lchars And Digits Then tempon = tempon & Mid$(txt, h, 1)
Next
OnlyChars = tempon
End Function
