Character Encoding Quick Guide

 
 
Encoding defines how the values of certain characters are represented, in terms of bits. Examples:
  • ASCII (American Standard Code for Information Interchange), a 7-bit character set.
  • ISO-8859-1, a 8-bit character set.
  • Unicode, a 16-bit character set.








ISO-8859-1



HTML and HTTP protocols make frequent reference to ISO Latin-1 and the character code ISO-8859-1. The HTTP specification mandates the use of the code ISO-8859-1 as the default character code that is passed over the network.

The term "ISO Latin-1" refers to a specific repertoire of "glyphs" (= "displayed characters") without reference to a particular encoding (= assigned to a value). ISO-8859-1 character code refers to ISO standard arrangement of ISO Latin-1 glyphs to code values. There are however other (non-ISO) encodings of the ISO Latin-1 glyphs. For example the IBM PC code page CP850.

ISO-8859-1 explicitly does not define displayable characters for positions 0-31 and 127-159, and the HTML standard does not allow those to be used for displayable characters. The only characters in this range that are used are 9, 10 and 13, which are tab, newline and carriage return respectively.

Note: ISO-8859-1 is also known as Latin-1.

To add the ® character in HTML, type:
  • &#decimal_value;

    For example: ®    

  • &#xhex_value;

    For example: ®
