What Is Unicode Urdu and Why Is It Useful?
Unicode is a worldwide standard that assigns a unique code to each character, including every Urdu letter, mark and digit.
Why it matters
Because the codes are standard, text typed on one device can be read on another: phones, laptops, websites and email. Search engines can also read Unicode text, which makes Urdu content findable.
How to tell if text is Unicode
Paste it into a plain text box or a web page. If the letters appear correctly in several places, it is almost certainly Unicode. Text from older programs may turn into strange symbols.
Using it
Type with an Urdu keyboard or the online Urdu editor, and save drafts as plain text or in a modern word processor.
Conclusion
Unicode is the practical default for Urdu on the modern web.
