Character sets define how text is encoded for web pages. In HTML, specifying the correct character set ensures proper display of text, including symbols, special characters, and multilingual content. The most commonly used character set is UTF-8, which supports nearly all characters from various languages and symbols.
At The Coding College, we help you understand how to use and define character sets in HTML effectively.
What Are Character Sets?
A character set is a collection of characters that a computer can recognize and render. This includes letters, numbers, symbols, and control codes. In HTML, character sets ensure that the browser interprets and displays text correctly.
Why Use UTF-8?
UTF-8 is the most widely used character set because:
- Global Compatibility: Supports a wide range of languages and symbols.
- Efficiency: Uses 1 to 4 bytes to represent characters, making it memory-efficient.
- Standardization: Recommended by the W3C and widely supported by modern browsers.
How to Declare a Character Set in HTML
The character set is declared in the <head> section of an HTML document using the <meta> tag.
Example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Character Set Example</title>
</head>
<body>
<p>This page uses the UTF-8 character set!</p>
</body>
</html>Common Character Sets
| Character Set | Description |
|---|---|
UTF-8 | Supports all characters, including emojis, symbols, and multilingual text. |
ISO-8859-1 | Used for Western European languages. |
UTF-16 | Supports a wider range of characters but uses more memory than UTF-8. |
HTML Character Encoding
Some characters need to be encoded to avoid conflicts with HTML syntax. For instance:
| Character | Entity Name | Entity Number |
|---|---|---|
< | < | < |
> | > | > |
& | & | & |
" | " | " |
' | ' | ' |
Example:
<p>Use <h1> for main headings in HTML.</p>UTF-8 in Action
UTF-8 enables the display of various special characters and symbols, such as emojis or foreign scripts.
Example:
<p>Smiley Emoji: 😀</p>
<p>Japanese Greeting: こんにちは</p>
<p>Math Symbol: ∑</p>Testing Character Sets
To ensure proper rendering:
- Use UTF-8 as the default character set.
- Save your HTML files with UTF-8 encoding in your text editor.
- Test the page in multiple browsers.
