About Lesson

HTML encoding, also known as character encoding, refers to the process of representing special characters, symbols, and non-standard characters in HTML using specific encoding schemes. It ensures that these characters are correctly interpreted and displayed by web browsers.

HTML uses Unicode as its character set, which is a universal character encoding standard that encompasses a vast range of characters from various writing systems. Unicode allows for the representation of characters from different languages and scripts, including special symbols, emojis, and non-ASCII characters.

To include special characters or characters outside the ASCII range in your HTML code, you need to use HTML entities or numeric character references. HTML entities are predefined character codes that start with an ampersand (&) and end with a semicolon (;). Here are a few examples:

< represents the less-than symbol (<).
> represents the greater-than symbol (>).
& represents the ampersand symbol (&).
" represents the double quotation mark (“).
© represents the copyright symbol (©).

Numeric character references are another way to encode special characters in HTML. They are represented by either decimal or hexadecimal values, preceded by an ampersand (&) and followed by a pound sign (#). For example:

< represents the less-than symbol (<).
> represents the greater-than symbol (>).
& represents the ampersand symbol (&).
" represents the double quotation mark (“).
© represents the copyright symbol (©).

By using HTML entities or numeric character references, you can ensure that special characters, symbols, and non-standard characters are correctly displayed in your HTML code, regardless of the encoding or browser settings. It’s important to select the appropriate encoding scheme based on the characters you want to represent and the HTML version you are using.
