+This class is capable of converting strings between two
8-bit encodings/charsets. It can also convert from/to Unicode (but only

+if you compiled wxWindows with wxUSE\_WCHAR\_T set to 1). Only limited subset

+{\tt wxFONTENCODING\_ISO8859\_1..15}, {\tt wxFONTENCODING\_CP1250..1257} and
+{\tt wxFONTENCODING\_KOI8}.
+
+\wxheading{Note}
+
+Please use \helpref{wxMBConv classes}{mbconvclasses} instead
+if possible. \helpref{wxCSConv}{wxcsconv} has much better support for various
+encodings than wxEncodingConverter. wxEncodingConverter is useful only
+if you rely on {\tt wxCONVERT\_SUBSTITUTE} mode of operation (see
+\helpref{Init}{wxencodingconverterinit}).
