No, all the files in the surce code were already in UTF-8. My system
is configured to treat UTF-8 as the default encoding. This is not an
encoding problem.

Yes, I have plans to ask for help in the brazilian Python mailing list
when I finish to prepare the C source code for this project. Then I
expect to receive help to translate the python modules for this new
language. There's a lot of work to do.

Thanks for the advice, you almost guessed what went wrong. I made some
tests and already discovered what's the problem. When I change
Grammar/Grammar, Python/ast.c and Modules/parsermodule.c to transform
"is not" in "not is", everything works fine and I create a new Python
verson where "a is not None" is wrong and "a not is None" is
right. But when I translate this to "não é", always happens a
SyntaxError. So the probles is really in the grammar checker that
can't handle some letters with accent.

Well, knowing where the problem is, I think that I can try to solve it
by myself. Thanks again.

Yes, I know. To a more "serious" programmer, it's essential to have a
basic understanding in english and would be better for him to start
with the real Python. But my intent is not to substitute Python in
Brazil, but to create a new language that could be learned easily by
younger people for educational purposes. My intent is to show them how
a computer software works. But surely I will warn my students that to
take programming more seriously, it's important to learn how to
program in some other language, like the original Python. But thanks
for the advice.
