I am adjoining a trivial program which works differently according to the encoding (UTF-8 or ISO-8859-1) of the source code, printing 1 or 2 as the answer.

GNAT has two switches that affect its way of looking at
coded characters in source text:
for identifiers in source text, specify -gnatiC
where C is one of the characters listed 3.2.10
of the GNAT UG accompanying the compiler;
for the wide character encoding method, specify -gnatWE
where E is one of the characters listed in the
same document.
With switch -gnatW8, I get
$ ./example
1
$
That is, the source text is understood to be encoded
in UTF-8, and 'ó' becomes Character'Val (243), viz. LC_O_Acute.
