Multibyte characters and wide characters

At first, the ``internationalization'' of ANSI C affected only library functions. However the final stage of internationalization -- multibyte characters and wide characters -- also affected the language proper.

This section is organized as follows:

• ````Asianization'' means multibyte characters''

• ``Encoding variations''

• ``Wide characters''

• ``Conversion functions''

• ``C language features''
