How to get proper special character from string in java?

Question

1. I am setting a special character in DataModel.
   My DataModel
   

   public class LaunchModel implements Serializable {
   
       private List<LaunchModel> testquestionList;
       public LaunchModel() {
       testquestionList=new ArrayList<LaunchModel>();
       }
       //GETTER AND SETTER
   }
   

   My controller method..

   private void setdefaultValues() {
   
       LaunchModel temp=new LaunchModel();
       List<LaunchModel> tempList=new ArrayList<LaunchModel>();
       temp.setQuestion("ΔLMN and ΔXYZ");

<h:form id="addAssessmentFormId" enctype="multipart/form-data">
    <t:div id="main" forceId="true">
        <t:dataList id="questionList" var="question"
            value="#{launchPlayer.launchModel.testquestionList}" rowIndexVar="index"
            layout="unorderedList" forceId="true">

            <t:div>

Answer 1

Set default encoding in your jsp. That should do.

<%@ page language="java" pageEncoding="utf8" contentType="text/html;charset=UTF-8" %>
