Note that unnecessary use of HTML character references may significantly reduce the readability of HTML. If the character encoding for a web page is chosen appropriately then HTML character references are usually only required for a few special characters. The characters '''&''' and '''<''' always need to be encoded, as noted above.

In [[XML]] there are five built-in character entity references:

* & = & (ampersand, U+0026)

* < = < (left angle bracket, less-than sign, U+003C)

* > = > (right angle bracket, greater-than sign, U+003E)

* " = " (quotation mark, U+0022)

* ' = ' (apostrophe, U+0027)

All other character entity references have to be defined before they can be used. For example, use of é (which gives é, Latin small letter E with acute, U+0039, in HTML) in an XML document will generate an error unless the entity has already been defined.
