I guess that the Rumpelstilskins of engineering will tell
you that those Portuguese characters are unnecessary. They
are not found on international keyboards anyway, right?
Or maybe they will refer you to a "solution" such as
pragma Source_File_Name.

Of course, Windows PC OS is the culprit, extending its technical
lead into Ada programming tools! Let's see what an "It Just Works"
Scottish computer has to say:

$ file fun��o_h.adb
fun��o_h.adb: UTF-8 Unicode text

$ gnatmake -gnatW8 -gnati8 fun��o_h.adb
gcc -c -gnatW8 -gnati8 fun��o_h.adb
gnat1(98261) malloc: *** mmap(size=1638400000) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
fun��o_h.adb:1:13: missing "("
compilation abandoned due to previous error
gnatmake: "fun��o_h.adb" compilation error

$ # The above is a process running out of memory in just a few secods

$ cat fun��o_h.adb
function Fun��o_H return Natural is
begin
   return 1;
end Fun��o_H;

Quite possibly you can inject a DOS into a source code
build system this way ;-)

Retro rulez.
