It may be possible, but until you tell us what hidden symbols are involved, we cannot progress further with this. Maybe the following macro will help identify them. Select the character and run the macro.
Code:
Sub AnsiCode()
Dim myData As DataObject
Dim vChar As Variant
Dim sCode As String
Set myData = New DataObject
For Each vChar In Selection.Characters
sCode = sCode & "ChrW(" & AscW(vChar) & ") & "
Next
sCode = Left(sCode, Len(sCode) - 3)
MsgBox sCode & vbCr & vbCr & "Copied to clipboard!"
myData.SetText sCode
myData.PutInClipboard
End Sub
