PHP Email Subject - in Japanese?

Question

Bit of an odd one, I know...
I've done a little site in Japanese, and everything works fine, apart from one thing...
I have a mail script for the contact form, but the Japanese tect I've entered for the email subject is incorrectly displaying as ありがとうござã&# 129;„ます。.
Its fine in English, just not liking the Japanese.
The code looks like:
//start Trigger_SendEmail1 trigger
//remove this line if you want to edit the code by hand
function Trigger_SendEmail1(&$tNG) {
  $emailObj = new tNG_Email($tNG);
  $emailObj->setFrom("[email protected]");
  $emailObj->setTo("{email}");
  $emailObj->setCC("");
  $emailObj->setBCC("");
  $emailObj->setSubject("ありがとうございます。");
  //WriteContent method
  $emailObj->setContent("{firstname} 様<br /><br />この度はヒーリングハウス　ハイジへのお問い合わせありがとうございます。<br /><br />スタッフが折り返し連絡しますので、今しばらくお待ち下さい。<br /><br />ヒーリングハウス　ハイジ");
  $emailObj->setEncoding("ISO-8859-1");
  $emailObj->setFormat("HTML/Text");
  $emailObj->setImportance("Normal");
  return $emailObj->Execute();
//end Trigger_SendEmail1 trigger
If anyone has any suggestions to get the subject to display correctly in the Japanese, that would be much appreciated!

The problem is that you're using Western European encoding, which supports only a limited range of characters. You should be able to use UTF-8 encoding:
Change this:
$emailObj->setEncoding("ISO-8859-1");
to this:
$emailObj->setEncoding("UTF-8");
If that doesn't work, try this:
$emailObj->setEncoding("Shift-JIS");
Shift-JIS is a Japanese-specific encoding. UTF-8 is Unicode, which supports most writing systems, including Japanese.
