If a username has invalid characters, it means that it includes symbols, spaces, or letters that are not permitted by the system's username policies. Typically, usernames are restricted to alphanumeric characters and specific symbols (like underscores or dashes) to ensure compatibility and security. Using invalid characters can lead to errors during account creation or login processes. Users should check the guidelines for acceptable username formats to resolve the issue.

When a username must consist of only 3 characters that can be letters and digits, it means that the name you choose must be exactly three characters long and can include any combination of alphabetic characters (A-Z, a-z) and numeric digits (0-9). This requirement is often implemented to ensure simplicity and uniformity in user identification. Additionally, limiting the length to three characters can help streamline account creation and management processes.

Most phrases can be understood by thinking about what each word means. Invalid means false, inaccurate. Birthday is the date of a person's birth. The phrase "invalid birthday" would most likely be seen on the Internet, on websites that ask a User to enter a birth date. Web designers often use the least words to make their statement. So "invalid birthday" is a quick way to alert a Website User to "check what you entered in the form, it seems wrong". Most often, a User forgot to change the year. As an example, no one can be born NOW or as yet on May 1, 2013.
