It would be possible to create utf8 -// library, but: -// - this requires review process first -// - in the case, when linking the a library which uses utf8 -// (say 'program_options'), user should also link to the utf8 library. -// This seems inconvenient, and asking a user to link to an unrevieved -// library is strange. -// Until the above points are fixed, a library which wants to use utf8 must: -// - include this header from one of it's headers or sources -// - include the corresponding .cpp file from one of the sources -// - before including either file, the library must define -// - BOOST_UTF8_BEGIN_NAMESPACE to the namespace declaration that must be used -// - BOOST_UTF8_END_NAMESPACE to the code to close the previous namespace -// - declaration. -// - BOOST_UTF8_DECL -- to the code which must be used for all 'exportable' -// symbols. -// -// For example, program_options library might contain: -// #define BOOST_UTF8_BEGIN_NAMESPACE <backslash character> -// namespace boost { namespace program_options { -// #define BOOST_UTF8_END_NAMESPACE }} -// #define BOOST_UTF8_DECL BOOST_PROGRAM_OPTIONS_DECL -// #include "../../detail/utf8/utf8_codecvt.cpp" -// -// Essentially, each library will have its own copy of utf8 code, in -// different namespaces. - -// Note:(Robert Ramey).
