I am using Woocommerce plugin for my e-commerce site. For mailing I've installed Postman SMTP.
I could not handle with Turkish characters on ongoing e-mails. Such characters "Şşğ..." on mail body I see "???" chars. I've tried to change charset of html mail to utf-8 by overriding email-header.php but no luck. I am also checking sent e-mail from my inbox. It's charset seems as utf-8.
Another point, Turkish characters are seemed supported on e-mail subject,
How could I get rid of this problem? Thanks
