issue with geting utf-8 characters

[RazzaghShahidi]

i got bad decoded json data.
my data are in persian and in my web are displayed well but in api getting bad characters.
for example:
i got in api :
{"manategh":[{"manategh_id":"51","manategh_name":"\u0634\u0644\u0645\u0686\u0647","manategh_picture":"24.jpg","manategh_description":"\u0645\u0648\u0642\u0639\u06cc\u062a \u062c\u063a\u0631\u0627\u0641\u06cc\u0627\u06cc\u06cc \u0634\u0644\u0645\u0686\u0647:\r\n\r\n\u0634\u0644\u0645\u0686\u0647 \u062f\u0631 \u06a9\u0634\u0648\u0631 \u0627\u06cc\u0631\u0627\u0646 \u060c \u0627\u0633\u062a\u0627\u0646 \u062e\u0648\u0632 }]}

i solved it by passing JSON_UNESCAPED_UNICODE to json_encode function.

file:
application\libraries\Format.php

in line 408:
return json_encode($data, JSON_UNESCAPED_UNICODE);
line 415:
return $callback.'('.json_encode($data, JSON_UNESCAPED_UNICODE).');';
line 422:
return json_encode($data, JSON_UNESCAPED_UNICODE);

and file:
application\libraries\REST_Controller.php
in line 1123:
... === TRUE ? json_encode($this->_args,JSON_UNESCAPED_UNICODE) : ...

@chriskacerguis I also hit this issue.
Searching from the issue tracker, there is need for it, but it was always just solved as work-around:
#675 #670 #622

Can we make that configurable,
so in future you won't need to change the libraries source code?

[luckydonald]

Like

if ($this->config->item('charset') == 'utf8') {
  return json_encode($data, JSON_UNESCAPED_UNICODE)
} else {
  return json_encode($data)
}
