Everything you need to know about HTML encoding and entity conversion
HTML encoding converts special characters like <, >, &, and " into their HTML entity equivalents (<, >, &, "). This prevents browsers from interpreting these characters as HTML markup, which is essential for security (preventing XSS attacks) and for displaying code snippets correctly on web pages.
Named entities use descriptive names like & for & and < for <. Numeric entities use character codes like & (decimal) or & (hexadecimal) for &. Both produce the same result, but named entities are more readable while numeric entities support a wider range of characters.
