Question

I’m trying to display the character š in a textbox, but it’s only displaying the other letters in the word. I’m grabbing data from a DB and, using json_encode, sending it via xmlhttp.responseText. When doing alert(xmlhttp.responseText) the character is coming up as \u009a, but in Unicode it says U+0161 is for š. Maybe this is the reason it’s not displaying correctly? I’m using Cpanel, and I’ve set all encodings for the DB to utf8, but it won’t let me change the encoding of the actual page from ascii. Maybe this is causing the letter to not be displayed?

Main page code:

function loadDoc()
{
   var xmlhttp;

   // code for IE7+, Firefox, Chrome, Opera, Safari
   if (window.XMLHttpRequest)
   {
      xmlhttp=new XMLHttpRequest();
   }
   // code for IE6, IE5
   else
   {
      xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
   }

   xmlhttp.onreadystatechange=function()
   {
      if (xmlhttp.readyState==4 && xmlhttp.status==200)
      {
         alert(xmlhttp.responseText);
         var a = JSON.parse(xmlhttp.responseText);
         document.getElementById("textbox").value=a.first;
         document.getElementById("textbox2").value=a.second;
         document.getElementById("textbox3").value=a.third;
         document.getElementById("textbox4").value=a.fourth;
         document.getElementById("textbox5").value=a.fifth;
         document.getElementById("textbox6").value=a.sixth;
      }
   }

   xmlhttp.open("GET","loadTextBox.php?id=4",true);
   xmlhttp.send();
}

loadTextBox.php code:

<?php
header("Content-type: application/json");

---Placeholder for correct DB login info---

$result = $mysql->query(---Placeholder for correct SQL query---);

while ($row = $result->fetch_object())
{
   $queryResult[] = $row->present_tense;
}
$textboxValue = $queryResult[0];
$textboxValue2 = $queryResult[1];
$textboxValue3 = $queryResult[2];
$textboxValue4 = $queryResult[3];
$textboxValue5 = $queryResult[4];
$textboxValue6 = $queryResult[5];
echo    
json_encode(array('first'=>utf8_encode($textboxValue),'second'=>
utf8_encode($textboxValue2),'third'=>utf8_encode($textboxValue3),'fourth'=>
utf8_encode($textboxValue4),'fifth'=>utf8_encode($textboxValue5),'sixth'=>
utf8_encode($textboxValue6)));
?>

Answer 1

Adding in the line

$mysql->query("SET CHARACTER SET 'utf8'");

inside loadTextBox.php after connecting to the DB and before the SQL query and removing the lines with utf8_encode fixed it.
