Hello friends, i need some suggestion for my endless localization problem.

I need to able to use my navigation menu like following:

users must see Turkish lable at menu item, but page must not use Turkish lable. For example:

My menu structure is below:

(Anasayfa) (Makaleler) (Modüller) (Temalar) (Hakkımızda) (Site Haritası)

Home Articles Modules Skins About Us  Sitemap

When search engines visit my webpage, they just can't find pages that contains Turkish character on pagename and the issue is being logged everytime in Admin> Logviewer (this makes logviewer as a recycle bin)

For example: http://domain.com/siteharitası.aspx is not being crawled by spiders because of ı character on pagename.

Is it possible to use Site Haritası at page label in menu but make it point to http://domain.com/sitemap.aspx

I checked this possibility and i noticed that  Admin menu items  localizations does not effect page names since they are existed

For example:

when i click Yönetim > Firmalar (Admin > Vendors) my browser goes to

http://domain.com/Admin/Vendors.aspx this is what i want for other menu items.
