Special symbol code for HTML webpages

In web design, we sometimes need to display the following two types of characters on the page:

1. Reserved characters in HTML.

2. a character that cannot be input on the keyboard but can express a special meaning.

Direct use is often not displayed, and the corresponding entity names or entity numbers must be used for display (the default character set in most browsers is the ISO-8859-1 ). The following is a preparation for fast query (note: the code is case sensitive ).
