ISO Latin 1
Officially named ISO-8859-1, a standard character set developed by the International Organization for Standardization (ISO). ISO Latin-1 is a superset of the ASCII character set and is very similar to the ANSI character set used in Windows, though the two are not identical. Both the HTTP and HTML protocols used on the World Wide Web are based on ISO Latin-1. This means that to represent non-ASCII characters on a Web page, you need to use the corresponding ISO Latin-1 code.
