/// \class sf::String
/// \ingroup system
///
/// sf::String is a utility string class defined mainly for
/// convenience. It is a Unicode string (implemented using
/// UTF-32), thus it can store any character in the world
/// (European, Chinese, Arabic, Hebrew, etc.).
///
/// It automatically handles conversions from/to ANSI and
/// wide strings, so that you can work with standard string
/// classes and still be compatible with functions taking a
/// sf::String.
///
/// \code
/// sf::String s;
///
/// std::string s1 = s; // automatically converted to ANSI string
/// std::wstring s2 = s; // automatically converted to wide string
/// s = "hello"; // automatically converted from ANSI string
/// s = L"hello"; // automatically converted from wide string
/// s += 'a'; // automatically converted from ANSI string
/// s += L'a'; // automatically converted from wide string
/// \endcode
///
/// Conversions involving ANSI strings use the default user locale. However
/// it is possible to use a custom locale if necessary:
/// \code
/// std::locale locale;
/// sf::String s;
/// ...
/// std::string s1 = s.toAnsiString(locale);
/// s = sf::String("hello", locale);
/// \endcode
///
/// sf::String defines the most important functions of the
/// standard std::string class: removing, random access, iterating,
/// appending, comparing, etc. However it is a simple class
/// provided for convenience, and you may have to consider using
/// a more optimized class if your program requires complex string
/// handling. The automatic conversion functions will then take
/// care of converting your string to sf::String whenever SFML
/// requires it.
///
/// Please note that SFML also defines a low-level, generic
/// interface for Unicode handling, see the sf::Utf classes.
