Codeigniter中的JQuery自动完成编码

Question

这适用于英文字符，但不适用于阿拉伯语。我打印查询与 “فف” 为$title，我发现了奇怪的字符，它是这样的：

SELECT * FROM users WHERE agent_id = 1 AND type LIKE "owner" AND (firstName LIKE "%\%D9\%81\%D9\%81%" OR lastName LIKE "%\%D9\%81\%D9\%81%") 

这里是我的代码： 控制器：

public function getResultExtend($title) {  
    $user_id = $this->session->userdata('id');   
    $result = $this->user->getOwners($user_id, $title);   
    foreach ($result as $user) { 
     $user->userName = utf8_encode(stripslashes($user->userName)); 
    } 
    echo json_encode($result); 
} 

查看：

$(document).ready(function(){ 
      $('#search').keypress(function(e){ 
       if(e.which == 13) 
       { 
        e.preventDefault(); 
       } 

       var searched = $('#search').val(); 
       var fullurl = $('#hiddenurl').val() + 'index.php/agent/getResultExtend/' + searched; 

       $.getJSON(fullurl,function(result){ 
        var elements = []; 

        $.each(result,function(i,val){ 
         elements.push({ value: this.ID, label: this.firstName+' '+this.lastName}); 
        }); 

        $('#search').autocomplete({ 
         source : elements, 
         select: function (event, ui) { 
          console.log(ui.item); 
         }, 
         focus: function(event, ui) { 
          $("#search").val(ui.item.label); 
          return false; 
         }, 
         select: function(event, ui) { 
          $("#search").val(ui.item.label); 
          $("#owner_id").val(ui.item.value); 
          return false; 
         } 
        });  

       }); 
      }); 
     }); 

型号：

function getOwners($user_id, $title) { 
    header('Content-Type:text/html; charset=UTF-8'); 
    //$title = iconv(mb_detect_encoding($title, mb_detect_order(), true), "UTF-8", $title); 
    $q = $this->db->query('SET NAMES utf8'); 
    $query = $this->db->query('SELECT * FROM users      
       WHERE agent_id = ' . $user_id . ' AND type LIKE "owner" 
       AND (firstName LIKE "%'.$this->db->escape_like_str($title).'%" 
       OR lastName LIKE "%'.$this->db->escape_like_str($title).'%") 
       '); 
    return $query->result(); 
} 

我的表排序规则是utf8_unicode_ci，列也是utf-8。 那么，问题在哪里？

检查排在你的application/config/database.php中：

$db['default']['char_set'] = 'utf8'; 
$db['default']['dbcollat'] = 'utf8_general_ci'; 

也尝试在你的.htaccess添加

AddDefaultCharset UTF-8 

或直接的index.php添加

header('Content-type: text/html; charset=utf-8');
