hi all ,
i enabled and use permalink in wordpress by /%postname%/ but in the IE when you click on one of my pages the URL shows in the address bar like this

"%d8%b1%d8%ae%d9%86%d9%87-%d8%a7%d9%85%d9%86%db%8c%d8%aa%db%8c-%d9%85%d8%b1%d9%88%d8%b1%da%af%d8%b1/"

but in the chrome it shows OK like this "www.mydomain.com/mobile-galaxy-s3"
also in the source code of that page for both browser you will see

<link rel="canonical" href="http://mydomain.com/%da%af%d9a%a%8c-%d9%86%d8%aa-2-%da%a9%d8%b1%d9%87/" />

my .htaccess is as follow :
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /ITnews
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>


# END WordPress
