한글인코딩확인방법2

한글인코딩을 사용시 매번 서버환경이 바뀔 때마다 확인하기 힘들다면...꼼수..ㅋㅋ

<form name="loginForm" id="loginForm" method="post" action ="" >
 <input name="encodingChk" type="hidden" value="한글인코딩 체크" />
 
 <input type="text" id="hangulName" name="hangulName" value="" />
 <input type="submit" value="로그인" /> 
</form>

++++++++  아래 수신받는 jsp 코드  ++++++++++
<%
String reqName = (request.getParameter("hangulName") == null) ? "" : request.getParameter("hangulName");
String encodingChk = (request.getParameter("encodingChk") == null) ? "" : request.getParameter("encodingChk");

// 한글인코딩 처리여부 확인....

String charset[] = {"utf-8","ms949","euc-kr", "ksc5601", "iso-8859-1", "8859_1", "ascii"};
boolean chkOk = false;
for(int i = 0; i < charset.length; i++){
 if(chkOk) break;
 for(int j = 0; j < charset.length; j++){
  String chkEncodingHangul = ChangeEncoding(encodingChk, charset[i], charset[j]);
