Hello!
I was working on my website project in XP. I want to do the same in FC6. What I was doing is
1) Using Macromedia Dream Weaver
2) Using a Personal Webserver DwebPro(Free for personal use) with PHP & SQL plugins.
3) Installed Unicode East Asian Languages Suppport and Phonetic Keyboard layout.
4) Installed URDU language fonts.

I was developing charset 'UTF-8' standard HTML webpages and writing URDU language as Unicode. For a quick hint you can view http://www.bbcurdu.com .

BUT after installing FC6 I thought to move my web project in FC6 but I can't even view the http://www.bbcursu.com exactly. I've enabled the URDU language support in FC6 but still can't see or write URDU correctly. Isn't it a drawback of Linux. So does it means that www.bbcurdu.com project is on Windows.

Did anyone have any idea for resolving my problem

Check if you have nls_utf8 support in your kernel:
lsmod | grep utf

If not, you can try loading it in as a module.
modprobe nls_utf8

Also go into the Gnome or KDE config and look at the keyboard setup. In kde you can select a new keyboard layout by selecting the country. I don't think that there is a phonetic layout (for Packistan). There is a default and urd (which may be the same as default).
