Subclause [localization] describes components that C++ programs may use to encapsulate (and therefore be more portable when confronting) cultural differences.

The locale facility includes internationalization support for character classification and string collation, numeric, monetary, and date/time formatting and parsing, and message retrieval.

The following subclauses describe components for locales themselves, the standard facets, and facilities from the C library, as summarized in Table 90.
