     wxFontEnumerator enumerates either all available fonts on the system or only
     the ones with given attributes - either only fixed-width (suited for use in
     programs such as terminal emulators and the like) or the fonts available in
-    the given encoding().

     To do this, you just have to call one of EnumerateXXX() functions - either
-    wxFontEnumerator::EnumerateFacenames or
-    wxFontEnumerator::EnumerateEncodings and the
-    corresponding callback (wxFontEnumerator::OnFacename or
-    wxFontEnumerator::OnFontEncoding) will be called
-    repeatedly until either all fonts satisfying the specified criteria are

+

+    Of course, if you call both of them, you should override both functions.
