\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 is easy to see comparing the last fragment with
the one above, this macro expands to nothing in the (usual) ANSI mode and
prefixes {\tt 'L'} to its argument in the Unicode mode.
Finally, there is a special \helpref{wxT()}{wxt} macro which should enclose all
literal strings in the program. As it is easy to see comparing the last

The important conclusion is that if you use {\tt wxChar} instead of
{\tt char}, avoid using C style strings and use {\tt wxString} instead and
don't forget to enclose all string literals inside {\tt wxT()} macro, your
don't forget to enclose all string literals inside \helpref{wxT()}{wxt} macro, your
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
they're already converted to the right representation (another standard
wxWindows macro {\tt \_()} does it, so there is no need for {\tt wxT()} in this
case) or you intend to pass the constant directly to an external function
which doesn't accept wide-character strings.
\item Always enclose literal string constants in \helpref{wxT()}{wxt} macro
unless they're already converted to the right representation (another standard
wxWindows macro \helpref{\_()}{underscore} does it, for example, so there is no
need for {\tt wxT()} in this case) or you intend to pass the constant directly
to an external function which doesn't accept wide-character strings.
\item Use {\tt wxString} instead of C style strings.
