title: PHP json_encode losing my UTF-8 escapes?
body: <p>I have an array with strings with international characters.<br />
  When I save this in the database I loose the backslashes? Why?</p>
  
  <pre><code>$descr_arr = array("héééllo","world");
  $js_encoded = json_encode($descr_arr);
  print $js_encoded; // "[\"h\u00e9\u00e9\u00e9llo\",\"world\"]"
  
  $sql_query = "UPDATE test_table SET description = '$js_encoded' WHERE id = 0";
  $sql_res = mysql_query($sql_query);
  
  // in the description field in the database I find:
  // ["hu00e9u00e9u00e9llo","world"]
  </code></pre>
