My application sends out emails to SMTP Server. The From alias of email has some french characters but they apear as ? in email.

These are settings on my unix box.

LANG=
LC_CTYPE=en_US.ISO8859-1
LC_NUMERIC=en_US.ISO8859-1
LC_TIME=en_US.ISO8859-1
LC_COLLATE=en_US.ISO8859-1
LC_MONETARY=en_US.ISO8859-1
LC_MESSAGES=C
LC_ALL=

As per these settings, the french characters should not be distorted.

Any help is appreciated.

Thanks.
