    wxT() is a macro which can be used with character and string literals (in other
    words, @c 'x' or @c "foo") to automatically convert them to Unicode in
    Unicode build configuration. Please see the
    @ref overview_unicode "Unicode overview" for more information.
    This macro is simply returns the value passed to it without changes in ASCII
    build. In fact, its definition is:

    @code
    #ifdef UNICODE
    #define wxT(x) L ## x
    #else // !Unicode
    #define wxT(x) x
    #endif
    @endcode

/**
    wxS is macro which can be used with character and string literals to either
    convert them to wide characters or strings in @c wchar_t-based Unicode
    builds or keep them unchanged in UTF-8 builds. The use of this macro is
    optional as the translation will always be done at run-time even if there is a
    mismatch between the kind of the literal used and wxStringCharType used in the
    current build, but using it can be beneficial in performance-sensitive code to
    do the conversion at compile-time instead.
