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

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
the one above, this macro expands to nothing in the (usual) ANSI mode and
prefixes {\tt 'L'} to its argument in the Unicode mode.
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 T()} macro, your
don't forget to enclose all string literals inside {\tt 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 T()} macro unless

they're already converted to the right representation (another standard

which doesn't accept wide-character strings.
\item Use {\tt wxString} instead of C style strings.
