Common use cases

  • Display a code example as literal HTML text.
  • Inspect numeric character references in an exported document.

Edge cases

  • The named list is limited: &copy; and unknown names stay unchanged. &nbsp; becomes a regular space, not a non-breaking space. There is no escape-all mode.
  • Decoding makes one pass: &amp;lt; becomes &lt;, not <. Missing semicolons and uppercase #X references remain unchanged.
  • Numeric values above U+10FFFF cause an error. Encoding an existing entity escapes its ampersand again; choose the mode that matches the input.

Features
