How to Add a Unicode Character to HTML?

You can add a Unicode character to an HTML document by creating an HTML entity from:

For example, the copyright symbol (©) is represented in the following way:

  • copy — named reference;
  • 169 — decimal numeric reference;
  • U+000A9 — hexadecimal numeric reference.

You can create an HTML entity from any of these in the following ways:

  • © — by adding the named reference between & and ;
  • © — by adding the decimal reference between &# and ;
  • © — by adding the hexadecimal reference between &#x and ;

Things to remember:

  • All HTML entities begin with an ampersand (&) and end with a semi-colon (;);
  • For numeric references (i.e. both, decimal and hexadecimal) you must add a hash (#) after the ampersand (&);
  • For hexadecimal references you must also prefix the hexadecimal number with x to indicate that the numbers that follow should be interpreted as hexadecimal;
  • For hexadecimal references, you may have noticed that U+000 was omitted from the entity. This is because U+ is merely used as a convention to denote that the hexadecimal digits that follow are Unicode code points, and this is never added to the HTML entity. The leading zeros, however, are optional to add.
