json encoding for unicode text in codeigniter

Question

I have created an array in my codeigniter controller and encoded as json as follows :

$templateText = $this->input->post('sampletext');
$template_sample = $this->input->post('sampletext');
$postdata = array('userid'          => LOGIN_FOR_TEMPLATE,
                    'password'          => PASWD_FOR_TEMPLATE,
                    'template'          => $templateText,
                    'template_sample'   => $template_sample,
                    'callback_url'      => base_url().'API/templateCallback'
                ); 

$postdata = json_encode($postdata); 
print_r($postdata);

if the $templateText is a unicode string, then the array is not encoded properly.

To test this I set this variable as :

$templateText = 'नये ऑफर 123';
$template_sample = 'नये ऑफर 123';

but my print_r() function display details as follows :

{"userid":"xxxx","password":"xxxx","template":"\u0928\u092f\u0947 \u0911\u092b\u0930 123","template_sample":"\u0928\u092f\u0947 \u0911\u092b\u0930 123","callback_url":"http:\/\/example.com\/API\/templateCallback"}

But I need to set it as 'नये ऑफर 123 like :

{"userid":"xxxx","password":"xxxx","template":"नये ऑफर 123","template_sample":"नये ऑफर 123","callback_url":"http://example.com/API/templateCallback"}

How do I solve this

I already set <meta charset="utf-8"> in my html

That's a fairly strange need...

Use it as

$postdata = json_encode($postdata, JSON_UNESCAPED_UNICODE);

You can use it as below for your URL

$postdata = json_encode($postdata,JSON_UNESCAPED_SLASHES|JSON_UNESCAPED_UNICODE);
