// wxNativeEncodingInfo contains all encoding parameters for this platform

// This private structure specifies all the parameters needed to create a font
// with the given encoding on this platform.
//
// Under X, it contains the last 2 elements of the font specifications
// (registry and encoding).
//
// Under Windows, it contains a number which is one of predefined XXX_CHARSET
// values (https://msdn.microsoft.com/en-us/library/cc250412.aspx).
//
// Under all platforms it also contains a facename string which should be
// used, if not empty, to create fonts in this encoding (this is the only way
// to create a font of non-standard encoding (like KOI8) under Windows - the
// facename specifies the encoding then)
