使用Javamail以意大利语发送邮件时看到的奇怪字符

Question

使用Javamail以意大利语发送邮件时，等于符号后看到的奇怪字符。有人建议使用javamail以意大利语发送邮件吗？

电子邮件正文如下

    
    
    
    
    Ciao Dibyendu Biswas,


    Abbiamo ricevuto una richiesta di reimpostazione della sua password Validac=
    tor.


    Rei=
    mposta Password


    Se ignori questo messaggio, la password non verr=C3=A0 reimpostata.


    Se non hai richiesto la reimpostazione della password, Comunicacelo 

    
    

以下是我用来发送邮件的java邮件代码。

    public static boolean sendMail (String emailId,String subject,String body,boolean isHtml) {

    boolean status = false;



    Properties properties = new Properties();
    properties.setProperty("mail.smtp.host", "smtp.zoho.com");
    properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
    properties.setProperty("mail.smtp.socketFactory.fallback", "false");
    properties.setProperty("mail.smtp.port", "465");
    properties.setProperty("mail.smtp.socketFactory.port", "465");
    properties.setProperty( "mail.pop3.socketFactory.fallback", "false");

    properties.put("mail.smtp.starttls.enable", "true");
    properties.put("mail.smtp.auth", "true");
    properties.put("mail.debug", "true");
    properties.put("mail.store.protocol", "pop3");
    properties.put("mail.transport.protocol", "smtp");
    properties.put("mail.debug.auth", "true");
    javax.mail.Session session = javax.mail.Session.getInstance(properties,new javax.mail.Authenticator() 
    {   @Override
        protected PasswordAuthentication getPasswordAuthentication() 
        {   return new PasswordAuthentication(ProductValidationSystemWebConstants.VALIDACTOR_SUPPORT_EMAILID,ProductValidationSystemWebConstants.VALIDACTOR_SUPPORT_PASSWORD);
        }
    });
    try 
    {   MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(ProductValidationSystemWebConstants.VALIDACTOR_SUPPORT_EMAILID));
        message.setRecipients(MimeMessage.RecipientType.TO,InternetAddress.parse(emailId));

        message.setSubject(subject);
        if(isHtml) {
            System.out.println("mail body before: "+body);
            message.setText(body,"UTF-8", "html");
            System.out.println("mail body after: "+body);
        }
        else
            message.setText(body);

        Transport.send(message);

        status = true;
    } 
    catch (MessagingException e) 
    {
        e.printStackTrace();
    }

    return status;
}

我用gmail来阅读邮件。如果邮件内容中有任何意大利字符，则会出现问题。
