How can I send an email formatted as "Name <user@example.com>" to:

ŠŒŽœžŸ¥µÀÁÃÄÅÆÇÉÊËÍÎÏÐÒÓÕÖØÙÜÝßàáâåæçèéëìíîïðñóôõöøùûýÿ <user@example.com>

Obviously, many of these characters will never show up in a name, but in case they do, I would prefer that they do not prevent an email from being successfully sent.

Currently, this fails as noted in Apache's error.log with

Ignoring invalid 'To:' recipient address '¥µÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýÿ ' Transaction aborted: no recipients specified

If possible, I would like to keep the special characters 'as they are.' Otherwise, can I use some sort of transliteration function to clean-up the name?

Example of usage:

 <?php
 $to = "ŠŒŽšœžŸ¥µÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýÿ <CHANGED@gmail.com>";
 $subject = "Test Subject";
 $body = "Test Body";
 if (mail($to, $subject, $body)) {
   echo("<p>Message successfully sent!</p>");
  } else {
   echo("<p>Message delivery failed...</p>");
  }
 ?>
