通过电子邮件发送特殊字符给Tumblr

Question

I'm using a PHP script to email a posting to Tumblr and Posterous. For Posterous special characters are showing up in the posting but for Tumblr it don't. (In general Tumblr does support special character - I tried it out with emailing from Gmail) So what could be the problem?

Here my PHP header:

$headers .= "MIME-Version: 1.0
"
           ."Content-Type: multipart/alternative; boundary=\"PHP-mixed-$bound_text\"
";

$message =  "--PHP-mixed-$bound_text
"
           ."Content-Type: multipart/related; type=\"text/html\"; boundary=PHP-mixed2-$bound_text

"
           ."--PHP-mixed2-$bound_text
"
           ."Content-Type: text/html; charset=\"utf-8\"
"
           ."Content-Transfer-Encoding: 7bit

";

I already tried several charsets and Content-Transfer-Encoding combinations without any different result.

Any ideas are welcome. Michael

I looked into how my GMail account sent it and found out it used windows-1252 for the charset and the text is base64 encoded (this may not be case in using other GMail accounts). The email I sent below was successfully posted by tumblr and I used the function utf8_decode to generate the correct base64 string.

$data = wordwrap(base64_encode(utf8_decode($stringWithSpecialCharacters)));

The raw email message is below:

To: [e-mail]
Subject: tumblr post from sudocode
from: omime class <[e-mail]>
MIME-Version: 1.0
Content-type: multipart/alternative;
    boundary=omime_1308940625_c0d4e36fd504619028804e8b23ceb12a


--omime_1308940625_c0d4e36fd504619028804e8b23ceb12a
Content-Type: text/plain; charset=windows-1252
Content-Transfer-Encoding: base64

I used my omime class to send the email and here's the code I used:

$email = new omime('alternative');
$email->attachText('ßÄÖùâêîôûëÿæœÙÂÊÎ');
$email->attachHTML('ßÄÖùâêîôûëÿæœÙÂÊÎ');

$email->send('[e-mail]', 'test tumblr post', 'from: omime class <[e-mail]>');
