Punycode is a type of encoding used to represent Unicode characters in ASCII. It was developed by the Internet Engineering Task Force (IETF) as part of the IDNA protocol, which stands for Internationalized Domain Name System.
Punycode enables domain names with international characters to be represented in an ASCII-compatible format, allowing them to be used on websites and other applications that don't support non-ASCII character sets.
The way Punycode works is by taking a domain name containing Unicode characters and converting it into an encoded version using only alphanumeric symbols from 0–9 and A–Z.
This allows browsers to recognize the address correctly even if they don't have access or support for all types of unicode scripts like Chinese or Japanese languages etc., making internationalization easier than ever before!.
Additionally, Punycodes are much shorter than their original form because they use fewer symbols; this makes them easier to remember when typing out URLs manually instead of copy pasting them each time you want visit a website!.
In summary, Punycode has revolutionized web development by enabling domains with special characters such as Chinese or Japanese language scripts can now easily be displayed online without any issues due its ability convert these strings into something compatible across different platforms - this means that developers no longer need worry about compatibility problems related internationalization when creating sites/apps!.
