Character entity references, or entities for short, enable you to use characters that cannot be expressed in the document's character encoding or that cannot be entered by a keyboard , e.g. copyright symbol ©.
What is HTML Entities
Some characters are reserved in HTML, e.g. you cannot use the less than (
<) or greater than (
>) signs or angle brackets within your text, because the browser could mistake them for markup, while some characters are not present on the keyboard like copyright symbol ©.
To display these special characters, they must be replaced with the character entities.
Frequently Used HTML Character Entities
|Result||Description||Entity Name||Numerical reference|
|non-breaking space|| || |
You can use numeric character references, instead of entity names. A key benefit of using numeric character references is that, they have stronger browser support, and can be used to specify any Unicode character, whereas entities are limited to a subset of this.
