Alt Key Table
Alt characters, or special characters, are symbols like ¿ © « ¤ ™ which can be created using Alt codes on computers that run Microsoft Windows operating systems.
These codes are generally typed onto a keypad along with the Alt key to create the special characters. Keyboards have limited space, so Alt codes enable the creation of characters and symbols that don’t already have designated keys.

Generally, special characters in meta tags do not have an effect on SEO. So, if a word or phrase needs its tilde, umlaut, or another accent to be understood, then keep the special character in place.
