Hi,

I'm running Mantis 1.1.6 (the one packaged in Debian "stable"), MySQL 5.0.51, apache 2.2.9, PHP 5.2.6
OS has UTF-8 locales configured
I tried the following with all "$g_phpMailer_method" possible values (0, 1, 2): same thing happens - just in case

• Symptom:
  French e-mails (both custom strings and user content) are badly encoded, thus, the following are not correctly displayed: é à ç ç â and so on

• some e-mails are built with:
  Content-Type: text/plain; charset="utf-8"
  example : When you send a reminder

• some with :
  Content-Type: text/plain; charset=""
  example : when you assign an issue to someone

• How I temporarily fixed it:
  I located in core/email_api.php, line 766:
  $mail->CharSet = $t_email_data->metadata['charset'];
  it must be empty sometimes

I forced it to:
$mail->CharSet = 'utf-8';

• A better solution ?
• Is it still happening in later releases ?
• What's the right fix in 1.1.6? (because hardcoding it the way I did is dirty I guess)
