Email address internationalization (EAI) is the use of non-ASCII characters in email addresses. EAI is necessary because the traditional ASCII character set used for email addresses does not support all of the world's languages.
Email addresses are typically in the format "user@domain", where "user" is the username of the email account and "domain" is the domain name of the email provider. The "@" symbol is used to separate the two parts of the address.
ASCII is a character encoding that includes only the English alphabet, numbers, and some punctuation marks. It does not support accented characters or other non-English characters. This means that email addresses containing such characters must be converted to a different format in order to work.
EAI addresses are typically in the format "user@domain", where "user" is the username of the email account, "domain" is the domain name of the email provider, and "eai" is the string "eai". This format is necessary because the traditional ASCII character set used for email addresses does not support all of the world's languages.
Converting an email address to EAI format is known as "internationalization", while converting an EAI address back to ASCII format is known as "normalization". Can email addresses have foreign characters? Yes, email addresses can have foreign characters. In fact, the vast majority of email addresses use foreign characters. For example, the email address "[email protected]" uses the foreign characters "oe" and "gmail.com". Are email addresses Unicode? Email addresses are not Unicode. They are ASCII. Is utf8 an email? No, utf8 is not an email. Email is a protocol for exchanging messages over the Internet. Utf8 is a character encoding that can be used in email messages, but it is not itself an email.
What are the 3 parts of an email address?
The three parts of an email address are the username, the domain name, and the top-level domain.
The username is the name of the account that you use to log in to the email service. It is usually your first initial and last name, or some combination of those.
The domain name is the name of the email service that you use. For example, Gmail's domain name is gmail.com.
The top-level domain is the domain that represents the country where the email service is located. For example, the top-level domain for Gmail is .com.
What are examples of email addresses?
Email addresses are typically in the format of username@domain, where "username" is the individual's login name for the email account, and "domain" is the domain name of the email provider. For example, a user with the login name "johnsmith" who uses the domain "gmail.com" would have the email address "[email protected]".
Other email providers use different formats for their email addresses. For example, Yahoo! Mail uses the format "[email protected]".
