in the function GESAOR, the wildcard * works only alone.
it should also work in a string like *abc* in order to transcribe all the codes which contain "abc"
there is a blocking error message when the external code and the internal code are the same. This should be a warning message only, because it can be usefull in order to prevent a transcription with a wildcard. For instance, internal code = "a", external code="*", except for "abc" which should remain "abc"
