+It specifies the charset used by the catalog. All strings in the catalog
+are encoded using this charset.
+
+You have to fill in proper charset information. Your .po file may look like this
+after doing so:

+\begin{verbatim}

+
+wxWindows is able to use this catalog under any supported platform
+(although iso8859-2 is a Unix encoding and is normally not understood by
+Windows).
+
+How is this done? When you tell the wxLocale class to load a message catalog that
+contains correct header, it checks the charset. The catalog is then converted
+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}.
