remove duplicates in a string regardless of its position in string

unlike my previous question,

i have also another file which has data like this in cell  025w@52/11711/89wB  i want to remove all duplicates and retain only unique values
so the desired correct result from the above string should be 0@789B

I would appreciate, help with built in formula and if not possible with formula, then UDF

or both of them if easy.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Please insert the following code into a VBA module.

Function RemoveDuplicateChars(rCells As Range) As String
  Dim sValue As String, sPos1 As String, sReturn As String
  Dim i As Integer, j As Integer, vCounter As Integer, vFound As Integer
  Dim aChars(99, 1)

  sValue = rCells.Value
  vCounter = 1

  For i = 1 To Len(sValue)
    sPos1 = Mid(sValue, i, 1)
    vFound = 0
    For j = 1 To 99
      If aChars(j, 0) = sPos1 Then
        aChars(j, 1) = 1
        vFound = 1
        Exit For
      End If
    If vFound = 0 Then
      aChars(vCounter, 0) = sPos1
      aChars(vCounter, 1) = 0
      vCounter = vCounter + 1
    End If
  For i = 1 To 99
    If aChars(i, 1) = 0 Then
      sReturn = sReturn & aChars(i, 0)
    End If

  RemoveDuplicateChars = sReturn
End Function

If the data is in cell A1 then use this formula in B1.
