What special characters are allowed in names?

Valid characters are uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), period (.), apostrophe ('), hyphen/dash (-), and spaces. No other characters are allowed.

What is a unique character on the keyboard?

A special character is one that is not considered a number or letter. Symbols, accent marks, and punctuation marks are considered special characters. Similarly, ASCII control characters and formatting characters like paragraph marks are also special characters.
