 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}

-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
