In a modern Internet community, many users are no longer satisfied with using only ASCII symbols to identify a domain name or a web resource. For example, they would like to be able to register a new domain using their native characters in Arabic or Chinese or to define a new URI using Unicode characters. That is why the internationalization of network resources is a cornerstone in widening horizons for the World Wide Web.
