# Boost.Locale

Part of the [Boost C++ Libraries](http://github.com/boostorg).

Boost.Locale is a library that provides high quality localization facilities in a C++ way.
It was originally designed a part of [CppCMS](http://cppcms.sourceforge.net/) - a C++ Web Framework project and then contributed to Boost.

Boost.Locale gives powerful tools for development of cross-platform localized software - the software that talks to users in their language.

Provided Features:

- Correct case conversion, case folding and normalization.
- Collation (sorting), including support for 4 Unicode collation levels.
- Date, time, timezone and calendar manipulations, formatting and parsing, including transparent support for calendars other than Gregorian.
- Boundary analysis for characters, words, sentences and line-breaks.
- Number formatting, spelling and parsing.
- Monetary formatting and parsing.
- Powerful message formatting (string translation) including support for plural forms, using GNU catalogs.
- Character set conversion.
- Transparent support for 8-bit character sets like Latin1
- Support for `char` and `wchar_t`
- Experimental support for C++11 `char16_t` and `char32_t` strings and streams.

Boost.Locale enhances and unifies the standard library's API the way it becomes useful and convenient for development of cross-platform and "cross-culture" software.

In order to achieve this goal Boost.Locale uses the-state-of-the-art Unicode and Localization library: ICU - International Components for Unicode.

Boost.Locale creates the natural glue between the C++ locales framework, iostreams, and the powerful ICU library.

Boost.Locale provides non-ICU based localization support as well.
It is based on the operating system native API or on the standard C++ library support.
Sacrificing some less important features, Boost.Locale becomes less powerful but lighter and easier to deploy and use library.
