For Each cha As Char In str.ToLower
If cha = “a” Then : cha = “ɐ”

ElseIf cha = “d” Then : cha = “p”
ElseIf cha = “e” Then : cha = “ə”
ElseIf cha = “f” Then : cha = “ɟ”

ElseIf cha = "(" Then : cha = ")"
ElseIf cha = ")" Then : cha = "("
ElseIf cha = "\" Then : cha = "/"
ElseIf cha = "/" Then : cha = "\"
ElseIf cha = ControlChars.Quote Then
strs = strs & ","
cha = ","
End If
strs = strs & cha
Next
Flip = Reverse(strs)
End Function

Usage: Flip(".[i__h4x].”)  would give, ˙[x4ɥ‾‾!]˙

Note: It uses the Reverse string function that i posted in order to reverse the flipped string

    Private Function Reverse(ByVal str As String) As String
If str.Length > 1 Then
Dim val As New System.Text.StringBuilder
For pos As Int32 = str.Length - 1 To 0 Step -1
val.Append(str.Chars(pos))
Next
Return val.ToString
Else
Return str
End If
End Function

Usage: Reverse(”i__h4x”), would give x4h__i
