/**
    This macro can be used with character and string literals (in other words,
    @c 'x' or @c "foo") to automatically convert them to wide strings in Unicode
    builds of wxWidgets. This macro 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

    Note that since wxWidgets 2.9.0 you shouldn't use wxT() anymore in your
    program sources if you want to support Unicode.

/**
    wxS is macro which can be used with character and string literals (in other words,
    @c 'x' or @c "foo") to either convert them to wide characters or wide strings
    in @c wchar_t-based (UTF-16) builds or keep them unchanged in @c char-based
    (UTF-8) builds.

    Basically this macro produces characters or strings of type wxStringCharType.

    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 the string or character type used in the current build.
    However using it can be beneficial in <b>performance-sensitive code</b> to
    do the conversion at compile-time instead.

    Don't confuse this macro with _()!
