php mail and accentuated characters

Hello I would like to send email from my php program. So I use the mail() function from php engine but I noticed that the accentuated characters were not well transmitted by php or the apache server (I use a linux box with FC4 and httpd server). In the phpinfo function, I saw the LANG environnement variable was set to en_US...., so I fixed it to fr_FR.... in the system file /etc/sysconfig/18n and reboot the machine, phpinfo gave me the correct french LANG. The result is still the same the apache server gave me incorrect languages in server-info, so I corrected the DefautLanguage directive and Priority Languages directives in the httpd.conf file. Restart apache and server-info gave me correct information, but the result is still the same. I am in trouble, because the mutt linux program send well the accentuated characters. I studied the difference between two mails, from mute and from php, and apparently the order definition after the Date aren't the same. I tried to use the phpmailer class, but the problem persists. I use php 4.3.10 The workaround I found is to use the mutt command from php by the system function, but it is a pity ! Do you know this problem ? thanks for your reply and happy new year to you !
