25 Localization library [localization]

25.1 General [localization.general]

This Clause 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 ISO C library, as summarized in Table 68.
