Laravel "Malformed UTF-8 characters, possibly incorrectly encoded", how to fix?

I try to return as json added attribute which I get with the following method in my User model but I keep getting 

 "message": "Malformed UTF-8 characters, possibly incorrectly encoded",
    "exception": "InvalidArgumentException",
    "file": "/var/www/timetool/vendor/laravel/framework/src/Illuminate/Http/JsonResponse.php",

the code 

   /**
     * @return string
     */
    public function getAvatarImageAttribute($value)
    {

        if($this->hasMedia('avatar')) {
             $image = $this->getMedia('avatar');
             $img = \Intervention\Image\ImageManagerStatic::make($image[0]->getPath())->encode('data-url');
         }
         elseif (isset($this->blob->dokument)) {
             $img = 'data:image/jpeg;base64,'. base64_encode($this->blob->document);
         } else {
             $img = '';
         }

         return $img;
    }

in controller I have 

return \Response::json($users, 200, array('Content-Type' => 'application/json;charset=utf8'), JSON_UNESCAPED_UNICODE);

Paste this function top of your document:

public static function convert_from_latin1_to_utf8_recursively($dat)
{
   if (is_string($dat)) {
      return utf8_encode($dat);
   } elseif (is_array($dat)) {
      $ret = [];
      foreach ($dat as $i => $d) $ret[ $i ] = self::convert_from_latin1_to_utf8_recursively($d);

      return $ret;
   } elseif (is_object($dat)) {
      foreach ($dat as $i => $d) $dat->$i = self::convert_from_latin1_to_utf8_recursively($d);

      return $dat;
   } else {
      return $dat;
   }
}

Call the above function to convert the content. It has a parameter just it need the value of blob image (binary):

$img = $this->convert_from_latin1_to_utf8_recursively($this->blob->document)

In my case the problem was the encoding of the controller. The solution was to convert it to UTF8 and the bug was fixed.

I'm thinking it's related to JSON needing only UTF8 chars and your blob may have invalid chars. Try utf8_encode($img). https://www.php.net/manual/en/function.utf8-encode.php In your controller just return. Laravel will build a proper json response for you.
