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.

  • Identical to ASCII for the first 127 characters
  • Does not use the characters from 128 to 159
  • Identical to ANSI and UTF-8 from 160 to 255

HTML 4 Example

<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1">

HTML 5 Example

<meta charset="ISO-8859-1">

The UTF-8 Character Set

  • is identical to ASCII for the values from 0 to 127
  • Does not use the characters from 128 to 159
  • Identical to ANSI and 8859-1 from 160 to 255
  • Continues from the value 256 to 10 000 characters
