IDN Punnycode converter

IDN Punnycode is a way to represent Unicode characters in ASCII format, using only letters, digits, and hyphens. It is used to convert domain names that contain non-ASCII characters into a form that can be entered into a web browser or used in a URL. An IDN Punnycode converter is a tool that converts a domain name with non-ASCII characters into Punnycode format. For example, if you have a domain name in Chinese characters, the IDN Punnycode converter would convert it into a string of ASCII characters that represents the same domain name. To convert a domain name to Punnycode, you can use an online IDN Punnycode converter or a command line tool such as "idn" on Unix-like systems. The conversion process involves converting each non-ASCII character in the domain name to its corresponding ASCII representation, and then adding "xn--" to the beginning of the resulting string. For example, the domain name "日本語.jp" (which means "Japanese" in Japanese) would be converted to "xn--wgv71a119e.jp" in Punnycode format. When entered into a web browser or used in a URL, this Punnycode string will be automatically converted back into the original Unicode characters, allowing users to access websites with non-ASCII domain names.
