+\membersection{wxT}\label{wxt}
+
+\func{wxChar}{wxT}{\param{char }{ch}}
+
+\func{const wxChar *}{wxT}{\param{const char *}{s}}
+
+wxT() is a macro which can be used with character and string literals (in other
+words, {\tt 'x'} or {\tt "foo"}) to automatically convert them to Unicode in
+Unicode build configuration. Please see the
+\helpref{Unicode overview}{unicode} for more information.
+
+This macro is simply returns the value passed to it without changes in ASCII
+build. In fact, its definition is:
+\begin{verbatim}
+#ifdef UNICODE
+#define wxT(x) L ## x
+#else // !Unicode
+#define wxT(x) x
+#endif
+\end{verbatim}
+
+\membersection{wxTRANSLATE}\label{wxtranslate}
+
+\func{const wxChar *}{wxTRANSLATE}{\param{const char *}{s}}
+
+This macro doesn't do anything in the program code -- it simply expands to the
+value of its argument (expand in Unicode build where it is equivalent to
+\helpref{wxT}{wxt} which makes it unnecessary to use both wxTRANSLATE and wxT
+with the same string which would be really unreadable).
+
+However it does have a purpose and it is to mark the literal strings for the
+extraction into the message catalog created by {\tt xgettext} program. Usually
+this is achieved using \helpref{\_()}{underscore} but that macro not only marks
+the string for extraction but also expands into
+\helpref{wxGetTranslation}{wxgettranslation} function call which means that it
+cannot be used in some situations, notably for the static arrays
+initialization.
+
+Here is an example which should make it more clear: suppose that you have a
+static array of strings containing the weekday names and which have to be
+translated (note that it is a bad example, really, as
+\helpref{wxDateTime}{wxdatetime} already can be used to get the localized week
+day names already). If you write
+\begin{verbatim}
+static const wxChar * const weekdays[] = { _("Mon"), ..., _("Sun") };
+...
+// use weekdays[n] as usual
+\end{verbatim}
+the code wouldn't compile because the function calls are forbidden in the array
+initializer. So instead you should do
+\begin{verbatim}
+static const wxChar * const weekdays[] = { wxTRANSLATE("Mon"), ..., wxTRANSLATE("Sun") };
+...
+// use wxGetTranslation(weekdays[n])
+\end{verbatim}
+here.
+
+Note that although the code {\bf would} compile if you simply omit
+wxTRANSLATE() in the above, it wouldn't work as expected because there would be
+no translations for the weekday names in the program message catalog and
+wxGetTranslation wouldn't find them.

+
+\membersection{\_}\label{underscore}
+
+\func{const wxChar *}{\_}{\param{const char *}{s}}
+
+This macro expands into a call to \helpref{wxGetTranslation}{wxgettranslation}
+function, so it marks the message for the extraction by {\tt xgettext} just as
+\helpref{wxTRANSLATE}{wxtranslate} does, but also returns the translation of
+the string for the current locale during execution.
+
+Don't confuse this macro with \helpref{\_T()}{underscoret}!
+
+
+\membersection{\_T}\label{underscoret}

+\func{const wxChar *}{\_T}{\param{const wxChar }{ch}}

+This macro is exactly the same as \helpref{wxT}{wxt} and is defined in
+wxWindows simply because it may be more intuitive for Windows programmers as
+the standard Win32 headers also define it (as well as yet another name for the
+same macro which is {\tt \_TEXT()}).
