First is the handling of alternative character sets that take into account all the writing systems of the world. Second, is how to specify languages and their unique presentation requirements within an HTML document. Many solutions presented by internationalization experts in a document called RFC-2070 were incorporated into the current HTML 4.0 Specification.

This chapter addresses both key issues for internationalization, as well as the new character set and language features in HTML 4.0.

Character Sets

The first challenge in internationalization is dealing with the staggering number of unique character shapes (called "glyphs”) that occur in all the writing sytems of the world. This includes not only alphabets, but all ideographs (characters that indicate a whole word or concept) for languages such as Chinese, Japanese, and Korean.
