Hi All,

I have a simple abc.txt email template under /etc/notification/email .

**************************abc.txt****************************

<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>

<body>
<pre style="white-space:normal;">
    <table width="100%" border="0" cellpadding="0" cellspacing="0" align="center">
         <br/><br/>
          ${pages} 
    </table>
</pre>
</body>
</html>

Whenever off time property will be changed the mail will be triggered. For this code is written as below.

In onevent we are calling below

emailService.sendEmail(EMAIL_TEMPLATE_PATH,emailParamsThirty,groupEmail);

******************************EMAIL CODE*********************************

private Map<String, String> prepareEmailParams(ResourceResolver resourceResolver, String pagePath)  {                
                final Map<String, String> emailParams = new HashMap<String,String>();        
                String pagePath = resourceResolver.map(page.getPath()); 
                strBufferPages.append("<li><a href='").append(pagePath).append(".html").append("'>");
                strBufferPages.append("第65回日");  --------THIS ONE WHEN WE WILL GET IN MAIL IT IS COMING LIKE ?65??
                strBufferPages.append("</a></li>");
                strBufferPages.append("</ul> </td></tr>");                
                //LOGGER.info("pagesExists ========== +++++++++++++ ==== " + strBufferPages.toString());
                emailParams.put("pages", strBufferPages.toString());                
    }

But When I am getting mail , the UTF-8 is removed and it is coming like ?65??

Can anybody please help me on this.

Thanks in advance.

Looks like an encoding issue. Set the encoding in the message content header - for example:

msg.setContent(message, "text/plain; charset=UTF-8");

Hi Scott,

Yes it is an encoding issue. I am using AEM 6.0 SP1. Also I have set the default parameter encoding as UTF-8 , as shown in below screenshot.

I am new to AEM. So can you please tell me where can I Set the below encoding in the message content header?

You might need to use the following:

sb.append(new String(bytes, charset));

Hi Srini,

I tried the code suggested by you in my java code. But still I am getting Question marks (?65??).

******************CHANGED CODE*******************

                String pageTitle1 = "第65回日";
                pageTitle1  = new String(pageTitle1.getBytes("UTF-8"));
                strBufferPages.append("<li><a href='").append(externLink).append(".html").append("'>");
                strBufferPages.append(pageTitle1);
                strBufferPages.append("</a></li>");
                strBufferPages.append("</ul> </td></tr>");

Hi Sunita,

1. Try to put the hard-coded Japanese string in the mail (abc.txt) directly and check if you are getting it right - if this is working, then it means you are not encoding it properly while setting the params

2. If above works, try setting the Japanese string only (new String(pageTitle.getBytes("UTF-8"))), then use the StringBuilder to append the full html.

Hi 

Pleas refer to this community article:-

Link:- http://adobeaemtips.blogspot.in/2015/11/utf-8-encoding-in-aem.html

// UTF- 8 Encoding in AEM

    AEM 6.1 : Go to Apache Sling Request Parameter Handling . Change the Default Parameter Encoding to "UTF-8"

    Encoding & Decoding while posting data to Sling Servlet :

    Decoding  in the Servlet.

    String id = java.net.URLDecoder.decode(request.getParameter("id"), "UTF-8");

    Encoding data before posting to a  Servlet

    String id= java.net.URLEncoder.encode("cust", "UTF-8"); 

    Set charset encoding in a JSP :

    <%@ page contentType="text/html;charset=UTF-8" %> 
    <%@ taglib uri="/libs/CFC/resources/jstl/c.tld" prefix="c" %> 
    <form method="post"> 
    <input name="searchterm" value="<c:out value="${param.searchterm}" />" />
    <input type="submit" /> 

    </form>

// Unicode escape sequences: \u followed by 4 hexadecimal digits (e.g.: \u0022 for ", \u0027 for ', \u003c for <, or \u003e for >

 In HTL (Formerly known as Sightly), 

 Use:-   ${ '{0} {1} {2} {3}' @ format=['\u003e','\u003C', '\u002F', '\u005C']}

 This will print :-        > < / \

I also faced similar issue. Unicode character(special characters) passed as a request parameter getting converted to question mark(?).

Reason : Reason is the character encoding.

Solution :

# Solution 1
1. Configure 'Apache Sling Request Parameter Handling', Set the property 'Default Parameter Encoding'='iso-8859-1'
2. Take care of the character encoding (to UTF-8) through code
queryString = new String(request.getParameter(initialSearchConfig.getQueryStringParamName()).getBytes("iso-8859-1"), "UTF-8");

# Solution 2
1.Configure 'Apache Sling Request Parameter Handling', Set the property 'Default Parameter Encoding'='UTF-8'
2. Igonore the encoding through code
queryString = new String(request.getParameter(initialSearchConfig.getQueryStringParamName()));

Hope this help.
