HTML Encoding (Character Sets)
To display an HTML page correctly, a web browser must know which character set to use.
The HTML charset Attribute
The character set is specified in the <meta> tag:
Example
<meta charset="UTF-8">
The HTML5 specification encourages web developers to use the UTF-8 character set.
UTF-8 covers almost all of the characters and symbols in the world!

The ASCII Character Set
ASCII was the first character encoding standard for the web.
It defined 128 different characters that could be used on the internet:
English letters (A-Z)
Numbers (0-9)
Special characters like ! $ + - ( ) @ < >.
The ANSI Character Set
ANSI (Windows-1252) was the original Windows character set:
Identical to ASCII for the first 127 characters
Special characters from 128 to 159
Identical to UTF-8 from 160 to 255
<meta charset="Windows-1252">
The ISO-8859-1 Character Set
ISO-8859-1 was the default character set for HTML 4. This character set
supported 256 different character codes. HTML 4 also supported UTF-8.
