传递阿拉伯参数的正确方法

Question

 <?php
   $tit = rawurldecode("نقفورالثاني-فوكاس");
   $cap = rawurldecode("الطريق-للقمة");
   ?>
   <a href = '<?php echo "road.php?title=$tit&caption=$cap" ; ?>'>

产生奇怪的％空格字符，如何正确发送阿拉伯语参数，它正在变为：

第一次是正确的，因为它通过干净的网址传递，但第二部分无论采用何种方法都无效：

RewriteCond %{THE_REQUEST} /road.php\?title=([^&\s]+)&caption=([^&\s]+)\s [NC]
RewriteRule . نقفورالثانيفوكاس/%1/%2/? [R=301,L]

RewriteRule ^نقفورالثانيفوكاس/([^/]+)/$ road.php?title=rawurldecode($1) [QSA,L]
RewriteRule ^نقفورالثانيفوكاس/([^/]+)/([^/]+)/$ road.php?title=rawurldecode($1)&caption=rawurldecode($2) [QSA,L]

非常感谢
