It only appears of display_errors is on though with 5.3.1+ you can also
detect it by looking at json_last_error()

Description:
------------
At my specific case, if a string contains an Euro symbol ( € ),
json_encode will return null for that string.

It might also happens with other special characters.

Reproduce code:
---------------
<?php

$array = array(
        'name' => htmlentities( 'My euro symbol €.' )
);

var_dump( $array );
var_dump( json_encode( $array ) );

Expected result:
----------------
array(1) {
  ["name"]=>
  string(29) "My euro symbol &euro;."
}
string(13) "{"name":"My euro symbol &euro;."}"

Actual result:
--------------
array(1) {
  ["name"]=>
  string(29) "My euro symbol &acirc;?&not;."
}
string(13) "{"name":null}"
