Example:
Private Sub Login()
Dim s as String
s = "Login"
End Sub
The obfuscator changes both Logins:
Private Sub o10101010101()
Dim s as String
s = "o10101010101"
End Sub
It is because of this Pattern in your code:
sPattern = "([\*\.\^\*\+\#\(\)\-\=\/\,\:\;\s\" & VBA.Chr$(34) & "])" & sFinde & "([\*\.\^\*\+\!\@\#\$\%\&\(\)\-\=\/\,\:\;\s\" & VBA.Chr$(34) & "]|$)"
Why exactly is there this VBA.Chr$(34)? Because of that Strings get obfuscated.
