Classes in the Internationalization Classes group let you internationalize your software with the convenient and easy-to-use framework of class RWLocale and RWAnsiLocale, and use class RWZone to manipulate time zones and daylight-saving time. With the exception of class RWBasicUString designed to handle 16-bit Unicode characters, the library is eight-bit clean, so you can use it with any eight-bit character set.

Chapter 7 explains the Internationalization Classes.
