Displaying Numbers in Native Scripts C#

For one of my web app i had to display numbers in native script, arabic in my case. After googling around, i found these two useful websites

UTF8Encoding.GetDecoder Method (MSDN)
JavaScript Unicode Charts

Navigate to the JavaScript Unicode Charts page, then select your preferred script from the dropdown menu(i'll follow the example for arabic). Then you'll be shown a Unicode script chart of your selected langauge.

The highlighted row in the above screenshot is the arabic numerals and D9A0 is the utf-8 encoding value for the arabic number 0, D9A5 will be the arabic number 5.
