电子邮件主题中的特殊符号

Question

我们目前正在研究一个缺陷，以允许在电子邮件主题中看到特殊符号。该电子邮件是text/html MIME类型。

目前，如果主题应该有心脏符号，它会显示为“&心脏”，但在电子邮件正文中会显示“心脏”符号。

有人可以帮助我们解决方案有特殊符号也是主题的一部分吗？

这是代码片段。

public boolean send(String to, String from, String subject, String templatePath, Map map) { 
// create a mime message using the mail sender implementation 
MimeMessage mimeMessage = mailSender.createMimeMessage(); 

// create the message using the specified template 
MimeMessageHelper helper; 
try 
{ 

    helper = new MimeMessageHelper(mimeMessage, true, "UTF-8"); 
    helper.setTo(to); 
    helper.setSubject(subject); 
    helper.setFrom(from); 

    String text = VelocityEngineUtils.mergeTemplateIntoString(engine, templatePath, map); 
    helper.setText(text, true); 
    send(mimeMessage); 
    log.debug("in send at start" + this.getClass().getName() 
      + ":SUCCESS: Sendig mail to" + to + " from " + from + " subject " 
      + subject); 
} catch (MessagingException e) 
{ 
    throw new MailPreparationException("unable to create the mime message helper", e); 
} catch (Exception e) 
{ 
    log.debug("in send at start" + this.getClass().getName() + ":Failed sending mail" 
      + to + " from " + from + " subject " + subject); 
    // throw new 
    // MailPreparationException("unable to create the mime message helper", 
    // e); 
} 
return false;

try

    Multipart multipart = new MimeMultipart(); 
    BodyPart bodyPart = new MimeBodyPart(); 
    multipart.addBodyPart(bodyPart);
