When I try to send a HTML encoded email from PHP, if the subject line contains special chars like "Here's the information you requested", PHP encodes it to read "Here's the information you requested."
How do I fix this?
Here's what the code looks like using PHP mail():
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'To: ' . $mod_params['name'] . '<' . $mod_params['email'] . '>' . "\r\n";
$headers .= 'From: <[email protected]>' . "\r\n";
$email_to = $mod_params['email'];
$email_sub = "Here's the Information You Requested";
$body = html_entity_decode("<html><body>" . $email_html_body . "</body></html>");
mail($email_to,$email_sub,$body,$headers);
It gives the same error as running it through the SugarPHPMailer class.

I had a similar issue in a Wordpress plug-in I was working on and I racked my brain over and over trying different suggestions from here and in various other Google search results. I finally found a solution that worked in my situation so I'll share it. I will say it was Paul's solution which I tried at first and it didn't work, but the reason was me trying to "shorthand" the solution. In my case just calling html_entity_decode() didn't work. Why? If I had read the PHP doc more closely it would have been obvious. My issue was with encoding on a single quote and the default for html_entity_decode() is 'ENT_COMPAT' which leaves single quotes alone. The solution was to set all the parameters and that worked. In reality I probably could have left off the charset since I was encoding UTF-8, but figured I be thorough.
$decoded_str = html_entity_decode ( $value_to_decode, ENT_QUOTES, 'UTF-8' );
The lesson here is a good one, "Read the docs". I'm not saying that you didn't (you probably did), but lot's of us get in a hurry and gloss over the solution which is sitting there staring us in the face if we'd only look.

Try this:
$newsubject='=?UTF-8?B?'.base64_encode($subject).'?=';
This way you don't rely on PHP or the MTA's encoding, you do the job, and the mail client should understand it. No special characters will be present in your new subject, so no problems should arise while delivering the email.
