Frequently asked questions

Is my HTML sent to a server?

No — encoding and decoding are simple string operations running in your browser.

Which characters get encoded?

The dangerous five (& < > " ') always; optionally every non-ASCII character as a numeric entity for maximum compatibility.

Which entities can be decoded?

Numeric entities (decimal and hex, including emoji) and the common named ones like &amp;, &lt;, &copy;, &mdash;.
