FAQ

Which characters must be escaped in HTML?

Always escape & and <. Escape > for readability, and " or ' when the text goes inside an attribute value. Escaping user input before putting it in a page is a basic defence against HTML injection.

What is the difference between named and numeric entities?

&copy; is a named entity, &#169; is decimal and &#xA9; is hexadecimal; all three produce the copyright sign. Numeric forms work for every Unicode character, while named ones exist only for a fixed list.

Does the decoder handle every named entity?

It handles all numeric entities and the most common named ones (&amp;, &lt;, &gt;, &quot;, &apos;, &nbsp;, &copy;, &euro;, arrows, quotes and more). Unknown names are left unchanged rather than guessed.
