PHP json_encode trunk string when using international character like é

This simple code show you the problem:

class MyObject
{
    var $publicString = "This is a weird character : é and it will trunk this sentence";
}
$myObject = new MyObject();
var_dump(json_encode($myObject));

The var_dump output is :

 string(47) "{"publicString":"This is a weird c开发者_如何学JAVAharacter : "}"

Why?

json_encode() expects UTF-8 data.

I assume your file is ISO-8859-1 encoded. ISO-8859-1 é is an invalid character in UTF-8.

A workaround would be storing the file as UTF-8, or doing an iconv():

$myObject->publicString = 
     iconv("iso-8859-1", "utf-8//IGNORE", $myObject->publicString);

var_dump(json_encode($myObject));

json_encode() only works with UTF-8 char set. Here's a link to an example on how to deal with this issue.
