Reference notes
How HTML encoding works
HTML encoding replaces special characters with entities so text can be displayed safely in markup.
Characters such as <, >, &, and quotes often need encoding depending on whether the text appears in body content or attributes.
HTML encoder examples
The text <strong>Hello</strong> can be encoded so it displays as text instead of becoming markup.
Attribute examples should also encode quotes to avoid breaking HTML attributes.
HTML encoder FAQ
HTML encoding is context-sensitive. Text content, attributes, scripts, and URLs have different escaping needs.
Encoding helps display text safely, but it is not a complete security policy by itself.
HTML encoder references
Reference material should cover HTML character references and escaping rules.
Future references can distinguish named entities, numeric entities, and modern browser parsing behavior.
HTML encoder developer examples
Developer examples should show encoding text before inserting it into HTML output.
Future examples can compare escaping for element text and attribute values.
