An ASCII domain name is a domain name that only contains characters from the English alphabet, numbers from 0-9, and hyphens with no other symbols. An example of an ASCII domain name is "beermoneyforum.com." Now you may see some website in chinese or different symbols. I think this falls under the IDN domain name. An Internationalized Domain Name (IDN) contains characters from other languages and scripts, such as Cyrillic, Japanese, or Chinese.
