Preguntas Frecuentes
What is the difference between named and numeric HTML entities?
Named entities use descriptive labels like & for '&' and < for '<'. Numeric entities use the character's Unicode code point, like & for '&'. Named entities are more readable, but numeric entities can represent any Unicode character.
When should I use HTML entity encoding?
Use encoding whenever you display user-generated content in HTML, show code examples on web pages, or include special characters that could be misinterpreted as HTML markup. This prevents rendering issues and security vulnerabilities.
Does encoding affect how text appears in the browser?
No. Browsers automatically render HTML entities as their corresponding characters. For example, & displays as '&' and < displays as '<'. The encoding is invisible to end users viewing the page.
