How is this done? When you tell the wxLocale class to load a message catalog that
-contains the header (msgid ""; normal .mo catalogs do {\bf not} contain it,
-you must remove the line with {\it fuzzy}!), it checks the charset. If the
-charset is "alien" on the platform the program is currently running (e.g.
-any of ISO encodings under Windows or CP12XX under Unix) it uses
-\helpref{wxEncodingConverter::GetPlatformEquivalents}{wxencodingconvertergetplatformequivalents}
-to obtain an encoding that is more common on this platform and converts
-the message catalog to this encoding. Note that it does {\bf not} check
-for presence of this encoding! It only assumes that it is always better to
-have strings in platform native encoding than in an encoding that is rarely
-(if ever) used.

-The behaviour described above is disabled by default.
-You must set {\it bConvertEncoding} to TRUE in
-\helpref{wxLocale constructor}{wxlocaledefctor} in order to enable
-runtime encoding conversion.

+to the charset used (see
+\helpref{wxLocale::GetSystemEncoding}{wxlocalegetsystemencoding} and
+\helpref{wxLocale::GetSystemEncodingName}{wxlocalegetsystemencodingname}) by
+user's operating system. This is default behaviour of the
+\helpref{wxLocale}{wxlocale} class; you can disable it by {\bf not} passing
+{\tt wxLOCALE\_CONV\_ENCODING} to \helpref{wxLocale::Init}{wxlocaleinit}.
