Sometimes it is also necessary to go from ANSI strings to wxStrings.
In this case, you can use the converter-constructor, as follows:
\begin{verbatim}
const char* ascii_str = "Some text";

\end{verbatim}
This code also compiles fine under a non-Unicode build of wxWidgets,
but in that case the converter is ignored.
