php - json_decode() returns non-readable text -

i have such code:

 ($j = 0; $j < mysql_num_rows($subcategoriesdata); $j++)     {       $subcategoriesstrresult = mysql_fetch_array($subcategoriesdata);       //echo $subcategoriesstrresult['title']."<br>";       $itemfeatures = array( $subcategoriesstrresult['title'] => $subcategoriesstrresult['path']);       array_push($arraydatasubcategoryitems, $itemfeatures);     };      array_push($mainarrayforjson, $item = array(                                                'parent_id' => $subcategoriesstrresult['parent'],                                                'level'     => $subcategoriesstrresult['level'],                                                'items'     => $arraydatasubcategoryitems     )); 

after $mainarrayforjson ready i'm trying check json-code simple echo

echo  json_encode($mainarrayforjson); 

meanwhile, sure need i'm checking single value of string echo (this string commented now) - works ok, see on chrome readable text (in database text stored in utf8, of course).

but last call echo check prepared json leads me next output:

[{"parent_id":"8-590","level":"3","items":[{"\u041c\u0435\u0442\u0430\u043b\u043b\u0438\u0447\u0435\u0441\u043a\u0438\u0439 \u043b\u043e\u0442\u043e\u043a baks (\u041f\u043e\u043b\u044c\u0448\u0430)":"8-590-1404"},{"\u041c\u0435\u0442\u0430\u043b\u043b\u0438\u0447\u0435\u0441\u043a\u0438\u0439 \u043b\u043e\u0442\u043e\u043a inpuk  

so, have no idea how fix - tried hardcode utf-coding "set names ..." , called header(), , iconv() - last has no sense becouse of i'm sured text in utf8.

please, help, thanks.

if want output text on web page, use javascript. , you'll russian characters. example:

<script type="text/javascript">     var = "\u041c\u0435\u0442\u0430\u043b\u043b\u0438\u0447\u0435\u0441\u043a\u0438\u0439 \u043b\u043e\u0442\u043e\u043a baks (\u041f\u043e\u043b\u044c\u0448\u0430";     alert(a); </script> 

outputs this:
