 The behaviour of all these functions is identical to the behaviour described
 there.
 
+You may notice that wxString sometimes has many functions which do the same
+thing like, for example, \helpref{Length()}{wxstringlength}, 
+\helpref{Len()}{wxstringlen} and {\tt length()} which all return the string
+length. In all cases of such duplication the {\tt std::string}-compatible
+method ({\tt length()} in this case, always the lowercase version) should be
+used as it will ensure smoother transition to {\tt std::string} when wxWindows
+starts using it instead of wxString.
