As a fact, I have been able to use identifiers like
�pfel for a very long time.

with Ada.Text_IO;
procedure T is
   type E is (�);
   �pfel : E := E'First;
begin
   Ada.Text_IO.Put_Line (E'Image (�pfel));
end T;

Enum_Type'Image (�) not outputting � is a bug in GNAT.

The Ada fact is that there are rules about character
case in identifiers.  Just like there are rules
about digits in numbers. There is no problem with
compiling the above: even though �pfel and �pfel use
different case, GNAT considers them the same
identifier, as should be.

You might be talking about Birnen or the phase
of the moon, I think.
