This can be achieved quite simply by using the means provided by wxWindows.
Basicly, there are only a few things to watch out for:
+
\begin{itemize}
\item Character type ({\tt char} or {\tt wchar\_t})
\item Literal strings (i.e. {\tt "Hello, world!"} or {\tt '*'})
\end{verbatim}
Of course, it would be nearly impossibly to write such programs if it had to
-be done this way (try to imagine the number of {\tt #ifdef UNICODE} an average

+What happens here? First of all, you see that there are no more {\tt \#ifdef}s
at all. Instead, we define some types and macros which behave differently in
the Unicode and ANSI builds and allows us to avoid using conditional
compilation in the program itself.
We have a {\tt wxChar} type which maps either on {\tt char} or {\tt wchar\_t}
depending on the mode in which program is being compiled. There is no need for
a separate type for strings though, because the standard
-\helpref{wxString}{wxstring} supports Unicode, i.e. it stores iether ANSI or
-Unicode strings depending on the mode.
+\helpref{wxString}{wxstring} supports Unicode, i.e. it stores either ANSI or
+Unicode strings depending on the compile mode.
Finally, there is a special {\tt wxT()} macro which should enclose all literal
strings in the program. As it's easy to see comparing the last fragment with
program automatically becomes (almost) Unicode compliant!
Just let us state once again the rules:
+
\begin{itemize}
\item Always use {\tt wxChar} instead of {\tt char}
\item Always enclose literal string constants in {\tt wxT()} macro unless
Unicode or ANSI strings and which thus makes it unnecessary to ever perform
any convertions in the program).
