php - Character encoding for French Accents

Question

I'm developing my first website for a French client and I'm having massive issues with accents being displayed as "?".After googling it for days, I thought I understood, but issues persists.

To simplify it, I'll explain just the email headers (the message contains french accents)

$headers  = 'MIME-Version: 1.0' . "
";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "
";

I've tried using charset UTF-8 and the iso-8859-1, but I still get this type of emails:

Merci pour votre int??r?at pour les tee shirts. 

Can any one help? I'm having these issues with mySql, HTML, PHP everywhere basically.

Thanks.

Answer 1

If intérêt shows up as int??r?at you likely (i.e. short of corruption due to double encoding) have UTF-8 encoded text being shown up as if it were ISO-8859-1.

Make sure the headers are correctly formed and present the content as being UTF-8 encoded.
