It means quite a bit, it requires not only that some method
be provided for representing all characters, but also that
the implementation define what this method is. This is from
Annex M:

    6  The coded representation for the text of an Ada program.
       See 2.1(4).

Note another example where there may be a difference between
source representation is in wide characters. It is quite
conceivable that the method, or set of methods, for representing
wide characters in source programs be different from the set
of methods usable in Text_IO. In the case of GNAT, there are
six different methods of representing wide characters, and all
are available for either source programs (by compiler option)
or for Text_IO (using a form parameter), but there is no
requirement that this be the case.
