special character
Punctuation or symbol
A special character is any character that isn't a letter, number, or space—punctuation marks, symbols, and operators like @, #, $, %, &, and *.
Password requirements often demand at least one special character for security.
In programming and regular expressions, certain special characters have reserved functions and must be escaped to be used literally: The ampersand is a special character in HTML.
