Câu hỏi thường gặp
What's the difference between named and numeric HTML entities?
Named entities like & are easier to read, while numeric entities like & or & (decimal or hex) work for any character, including ones without a named entity. Both render identically in a browser.
When do I actually need to encode HTML entities?
Encode characters like < > & " ' whenever you're inserting user-provided or dynamic text into HTML markup, so the browser treats them as text rather than as part of a tag or attribute.
What's the difference between "Basic" and "All characters" mode?
Basic only escapes the characters that are structurally significant in HTML (like < > & " '), while "All characters" also converts other non-ASCII characters to numeric entities, which can be useful for older or strict parsers.
