In this section, we discussed a variety of issues involved in developing software for worldwide use. For all of these areas in which cultural conventions differ from one region to another, the C++ Standard Library provides services that enable you to easily internationalize your C++ programs. These services include:
Formatting and parsing of numbers, currency units, dates, and times
Handling different alphabets, their character classification, and collation sequences
Converting codesets, including multibyte to wide character conversion
Handling messages in different languages.
