    @class wxString

    The wxString class has been completely rewritten for wxWidgets 3.0
    and this change was actually the main reason for the calling that
    version wxWidgets 3.0.

    wxString is a class representing a Unicode character string.
    wxString uses @c std::basic_string internally (even if @c wxUSE_STL is not defined)
    to store its content (unless this is not supported by the compiler or disabled
    specifically when building wxWidgets) and it therefore inherits
    many features from @c std::basic_string. (Note that most implementations of
    @c std::basic_string are thread-safe and don't use reference counting.)

    These @c std::basic_string standard functions are only listed here, but
    they are not fully documented in this manual; see the STL documentation
    (http://www.cppreference.com/wiki/string/start) for more info.
    The behaviour of all these functions is identical to the behaviour
    described there.

    You may notice that wxString sometimes has several functions which do
    the same thing like Length(), Len() and length() which all return the
    string length. In all cases of such duplication the @c std::string
    compatible methods should be used.

    For informations about the internal encoding used by wxString and
    for important warnings and advices for using it, please read
    the @ref overview_string.

    Since wxWidgets 3.0 wxString always stores Unicode strings, so you should
    be sure to read also @ref overview_unicode.

    @class wxStringBufferLength

    This tiny class allows you to conveniently access the wxString internal buffer
    as a writable pointer without any risk of forgetting to restore the string to
    the usable state later, and allows the user to set the internal length of the string.

    For example, assuming you have a low-level OS function called
    @c "int GetMeaningOfLifeAsString(char *)" copying the value in the provided
    buffer (which must be writable, of course), and returning the actual length
    of the string, you might call it like this:

    @code
        wxString theAnswer;
        wxStringBufferLength theAnswerBuffer(theAnswer, 1024);
        int nLength = GetMeaningOfLifeAsString(theAnswerBuffer);
        theAnswerBuffer.SetLength(nLength);
        if ( theAnswer != "42" )
            wxLogError("Something is very wrong!");
    @endcode

    Note that the exact usage of this depends on whether or not wxUSE_STL is
    enabled. If wxUSE_STL is enabled, wxStringBuffer creates a separate empty
    character buffer, and if wxUSE_STL is disabled, it uses GetWriteBuf() from
    wxString, keeping the same buffer wxString uses intact. In other words,
    relying on wxStringBuffer containing the old wxString data is not a good
    idea if you want to build your program both with and without wxUSE_STL.

    Note that wxStringBuffer::SetLength @b must be called before
    wxStringBufferLength destructs.
