In Portuguese-Brazilian we some accents in some
letters... for instance ç, á, à, ã, õ, é... etc, etc.
Well, I receive some e-mails from Brazilain and
American friends without a problem. For instance:
Informativo da Arte e Cultura.
Pretendemos, neste Informativo, dar-lhes a
conhecer dos
I would start first by finding out what program each person used to
email you in the first place and also whether it was sent in plain text
or HTML. How the accents are being created in the problem computer might
make a difference. Is the sender going through a corporate email
security program
