Character references
A character reference is an XML-style reference to a Unicode character that is identified by its decimal or hexadecimal code point.
A character reference begins with either
&#x or &# and
ends with a semicolon (;). If the character reference begins with &#x,
the digits and letters up to the terminating semicolon (;) provide
a hexadecimal representation of the character's code point in ISO/IEC
10646. If the character reference begins with &#,
the digits up to the terminating semicolon (;) provide a decimal representation
of the character's code point.Example
The character reference € represents
the Euro symbol (€).
