HTML Entities
Some characters are reserved in HTML.It is not possible to use the less than (<) or greater than (>) signs in your text, because the browser will mix them with tags.
To actually display reserved characters, we must use character entities in the HTML source code.
A character entity looks like this:
&entity_name;
OR
entity_number;
To display a less than sign we must write: < or <
Tip: The advantage of using an entity name, instead of a number, is that the name is easier
to remember. However, the disadvantage is that browsers may not support all entity names (the support for entity numbers is very good).
Non-breaking Space
A common character entity used in HTML is the non-breaking space ( ).Browsers will always truncate spaces in HTML pages. If you write 10 spaces in your text, the browser will remove 9 of them, before displaying the page. To add spaces to your text, you can use the character entity.

Modern browsers supports several character-sets:
ASCII character set
Standard ISO character sets
Mathematical symbols, Greek letters, and other symbols
ISO-8859-1
ISO-8859-1 is the default character set in most browsers.The first 128 characters of ISO-8859-1 is the original ASCII character-set (the numbers from 0-9, the uppercase and lowercase English alphabet, and some special characters).
The higher part of ISO-8859-1 (codes from 160-255) contains the characters used in Western European countries and some commonly used special characters.
Entities are used to implement reserved characters or to express characters that cannot easily be entered with the keyboard.
Reserved Characters in HTML
Some characters are reserved in HTML and XHTML. For example, you cannot use the greater than or less than signs within your text because the browser could mistake them for markup.HTML and XHTML processors must support the five special characters listed in the table below:

---|---|---|---|
