Windows XP does not support Urdu language by default unless the following steps are carried out. Workaround:
- Adding Urdu Keyboard
- Open "Regional and Language Options" from Control Panel OR from Start Menu -> Run "intl.cpl".
- Choose Language tab.
- Check the "Install files for Complex Script and right-to-left languages (Including Thai)".
- Press Apply to proceed.
- Click "Details" button.
- Click on "Add" button from "Input Language" list box select Urdu.
- Press OK
Now you can type Urdu text after selecting it from the taskbar.
Note: Urdu has 6 additional characters in its keyboard more than the Arabic keyboard.
