Before writing an internationalized Client-Library application, you must decide how the application will localize, that is, how it will determine which language, character set, and cultural conventions to use in a given environment.
Client-Library applications can use initial localization values, custom localization values, or both.
Most applications use initial localization values.
For information about how initial localization values are determined and how to decide whether your application can use them, see “Deciding what localization values to use”.
