नमस्ते दुनिया

  var iString = "नमस्ते दुनिया", oString ="";
  for (var i=0; i<iString.length; i++) {
    oString += (iString.charCodeAt(i)<=127)? iString.charAt(i) : '&#' + iString.charCodeAt(i) + ';': 
  }

var translateLatin2Hindi = { 
"Namaste Duniya":"नमस्ते दुनिया",
,
,

"Duniya Namaste":"दुनिया नमस्ते"
}

var translateHindi2Latin = {}
for (var o in translateLatin2Hindi) {
  translateHindi2Latin[translateLatin2Hindi[o]]=o;
}

function getHindi(latinString) {
  var val = translateLatin2Hindi[latinString];
  return (val)?val:"Not found";
}    
function getLatin(hindiString) {
  var val = translateHindi2Latin[hindiString];
