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' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
I've tried using charset UTF-8 and the iso-8859-1, but I still get this type of emails:
Merci pour votre intérêt pour les tee shirts.
Can any one help? I'm having these issues with mySql, HTML, PHP everywhere basically.
Thanks.
If intérêt shows up as intérêt 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.
First of all, make the charset in the header UTF8 again.
In your page, use utf8_encode() where appropriate to make sure values coming from a database or external files are properly encoded (try to set the encoding of the fields in your database to UTF8 as well)
Also, take a look at the htmlentities() function to parse special characters to html entities which may solve encoding issues as well.
All other languages except French work fine for me by default
In my /fr/messages.php file I was able to resolve this with
'myKey' => utf8_encode('en français'),
