GNAT and ISO 10646 (UTF) characters

GNAT and ISO 10646 (UTF) characters

[Georg Bauhaus]

Using -gnatW8 and -gnati8 works just fine when
an input file is using international characters.

Gnatstub does not seem to know about the same international
characters, though.  Or have I just missed the options
I should specify?

Some hodgepodge source text (encoded using UTF-8) for the
sake of an example (with apologies to the French):

package Largeur is

    type Metre is delta 0.001 digits 9 range 0.0 .. 10_000.0;

    function Imprimé (C : Character) return Metre;

end Largeur;

I forgot, sorry:

$ gnatstub -v largeur.ads

gnatstub: cannot create the tree file for largeur.ads

And when trying to work around the illegal character
by (naively) reusing the tree file built by GNAT, I get

$ gnatstub -v -r largeur.ads
GNATSTUB (built with ASIS 2.0.R for GNAT GPL 2009 (20090519))
Copyright 1997-2009, Free Software Foundation, Inc.

Unexpected bug in GNATSTUB (built with ASIS 2.0.R for GNAT GPL 2009 
(20090519))
ASIS.EXCEPTIONS.ASIS_INAPPROPRIATE_CONTEXT raised
gnatstub: ASIS Diagnosis is Unopened Context argument in 
Asis.Extensions.Main_Unit_In_Current_Tree
gnatstub: Status Value   is VALUE_ERROR

Please report to ...@gnat.com

Which I'll do.

Sorry for creating more noice, I had not seen gcc_switches,
i.e. -cargs, which can be specified on the gnatstub command
line. However, the result is still Latin-1 output. International
wide_string  "€" (the EUR sign) becomes " " (blank).
Has anyone used this and can tell me what I'm doing wrong?
