Wrong charachters

Hi Guys.
I'm newbie in mimedefang and am having a little problem.
Everything works fine, but the warning text shows wrong characters.
My  OS  language  is  pt_BR.UTF-8  and  the  erros  are in 'ç' 'á' for
example, but inside 'warning1.txt' file everything is correct.
Does someone have experimented this issue before? tks
