How can I send cyrillic emails with Mandrill and Windows1251 encoding?

Question

I have started to use Mandrill to send all mails from our site but faced a problem with encoding.

Encoding of the site is still Windows1251 / CP-1251 (I really don't have time to change it). I can send emails in English. But when I try to send cyrillic emails (Ukrainian, Russian, etc) it shows me an error "You must specify a key value...".

I need always to encode body of email to UTF-8. In this case Mandrill sends letter well but emails are with broken encoding.

Does somebody know if it possible to send emails with Mandrill using Windows-1251 charset? How can I fix it? Any advice will be useful!

Code is below:

require_once "all-sdk/mandrill/src/Mandrill.php";
$message_txt = utf8_encode($message);

try {
    $mandrill = new Mandrill('my_api_key_here');
    $message = array(
        'html' => $message_txt,
        'text' => 'Example text content',
        'subject' => 'example subject',
        'from_email' => '[email protected]',

Found! To send cyrillic (cp1251) emails in Madrill just use iconv-function before any API-call.

$message_txt = iconv('windows-1251','UTF-8',$message);
$subject = iconv('windows-1251','UTF-8',$subject);
