  Character entity references in HTML 4
A character entity reference is an SGML construct that references a character of the document character set.
24.2 Character entity references for ISO 8859-1 characters
The character entity references in this section are for escaping markup-significant characters (these are the same as those in HTML 2.0 and 3.2), for denoting spaces and dashes.

 HTML Character Entity References - HTML Code Tutorial
A character entity reference consists of an ampersand (and), followed by a pound sign (#), the number of the character entity, and finishing with a semi-colon (;).
The names of character entities are not as well supported by the browsers as the numbers, so it's best to use the numbers.
Character entity references work in many situations without the semi-colon, but not in others.

 Character encodings in HTML - Wikipedia, the free encyclopedia
The character encoding is often referred to as the "character set" and it indeed does limit the characters in the raw source text.
However, the HTML standard states that the "charset" is to be treated as an encoding of Unicode characters and provides a way to specify characters that the "charset" does not cover.
However, for backward compatibility with early HTML authors and browsers that ignored this restriction, raw characters and numeric character references in the 80–9F range are interpreted by some browsers as representing the characters mapped to bytes 80–9F in the Windows-1252 encoding.

 HTML 4 Entities
Character entity references, or entities for short, provide a method of entering characters that cannot be expressed in the document's character encoding or that cannot easily be entered on a keyboard.
While entities are limited to a subset of Unicode characters, numeric character references can specify any character.
Numeric character references may be given in decimal or hexadecimal, though browser support is stronger for decimal references.

 HTML 4.0 Entities for Symbols and Greek Letters
The following table gives the character entity reference, decimal character reference, and hexadecimal character reference for symbols and Greek letters, as well as the rendering of each in your browser.
Glyphs of the characters are available at the Unicode Consortium.
These entities are all new in HTML 4.0 and may not be supported by old browsers.

 Adrian Roselli — A Simple Character Entity Chart
For those who use characters in their copy that don't normally appear on the keyboard, it's always been a hit-and-miss game of tracking down the ISO character entity and choosing between the named and numeric value.
The W3C character entity reference is certainly definitive, but not practical.
Display of glyphs for these characters may be obtained by being able to display the relevant [ISO10646] characters or by other means, such as internally mapping the listed entities, numeric character references, and characters to the appropriate position in some font that contains the requisite glyphs.

 HTML Character Reference - HTML with Style - Webreference.com
The internationalization of the Web is moving at a slow pace down a bumpy road, and using the characters described in the three tables of this reference is not always straightforward.
For a gentle and practical introduction to HTML and characters, you can do much worse than reading our own Tutorial 17, which explains UCS and Unicode, character sets and character encodings, and numerical character references and character entity references.
The entities described here are defined in the HTML 4.0 specification as well as the XHTML 1.0 specification if you feel like sorting through DTDs.

 XML.com: Entity and Character References
The wish to leave entity references alone can't be granted completely, because redefining an XML parser's responsibilities is outside of the scope of the W3C XSL Working Group's responsibilities.
A numeric character reference is a way to indicate a character by using its code point number; no declaration is necessary, so it's not a named unit of storage, and therefore not an entity.
That's not an entity, it's a numeric character entity reference, but like an entity reference, the XML parser that hands the source document to the XSLT processor is required by the XML Recommendation to map it to the appropriate character of the result document in the result document's encoding if it can.

 "Character references" explained
The fact that in HTML, both character references and entity references begin with the ampersand symbol is just coincidental, or a pragmatic choice, rather than any deep connection.
A similar jump to a wrong conclusion is with entity references and character references, thanks to ERO ("Entity Reference Open") and CRO ("Character Reference Open") sharing the same first character in the RCS bindings (respectively, "and" and "and#").

HTML 4 includes around 250 special characters, or character entities, such as § ± ¶ and ‡.
HTML version 4, which is the version most of use every day, includes roughly 250 special characters.

 Character References Explained - Lachy’s Log
For example, using a control character in the range from 0 to 31 (except for tab, newline and carriage return) either directly or with a numeric character reference results in a well-formedness error.
Character entity references can be used in HTML and in XML; but for XML, other than the 5 predefined entities, need to be defined in a DTD (such as with XHTML and MathML).
It is recommended that you stick with the 5 predefined entity references and numeric character references, or use a Unicode encoding.

 HTML special character reference
The following HTML 4 character reference table can be used to enter such special characters using the associated "numeric character reference" code or the "character entity reference" code.
Numeric character reference ("ID" column in the table) is the numeric representation of a given character.
Character entity reference ("Code" column in the table) is the standard name of a given character.

In addition there are many ISO-Latin 1 characters that you may wish to include in a document, but which are not trivially available on a standard keyboard.
Entity references are similar, but use symbolic names to represent the characters.
The ISO data table document lists all the ISO Latin-1 characters, alongside their numerical positions in the character set (both decimal -- used by HTML character references, and hexadecimal -- used by URL character encodings) and the corresponding entity reference, if defined.

However, differences in the characters supported by localised keyboards mostly don't allow for such special characters to be directly typed into a HTML document.
The entire characters set may be included in a HTML document, by referencing them with their number in the ISO-8859-1 character set, with certain commonly used characters being supported by a more memorable entity name.
Numerical entity references enjoy more widespread support, so it is generally safer to use the corresponding entity number if you can not guarantee your viewers browser version.

You can use it to replace named entity references with numerical ones for older browsers that don't understand all of the HTML4 named entities, and you can also use it to insert character references of any kind into your documents by looking up the character and using the number or entity name.
Note that the first 33 characters are control codes and are essentially unused in modern computer systems, except for the space, tab, linefeed and carriage return characters.
The characters numbered 128 to 159 inclusive are also unused, but are shown here because Microsoft Windows fonts using the Windows-1252 Western European encoding contain characters in these positions, some of which are useful (like the trademark sign and the angle quotes).

Replace with the appropriate HTML character entity reference, if there is one; otherwise replace with a numeric character reference.
Generally, for components generating HTML output, it sufficient to set output_encoding to 'latin1' (or even 'ascii'), and encoding_errors to 'htmlentityreplace'.
(Latin1 is the default encoding for HTML, as specified in RFC 2616.) The 'htmlentityreplace' error handler replaces any characters which can't be encoded by an HTML named character reference (or a numeric character reference, if that is not possible) so this setting can correctly handle the output of any unicode character to HTML.
