 The second form is used when retrieving translation of string that has

-It is also used as the key for the search in the catalog.

 Both versions call \helpref{wxLocale::GetString}{wxlocalegetstring}.
 
+Note that this function is not suitable for literal strings in Unicode
+builds, since you the literal strings must be enclosed into 
+\helpref{\_T()}{underscoret} or \helpref{wxT}{wxt} macro which makes them
+unrecognised by \texttt{xgettext}, and so they are not extracted to the message
+catalog. Instead, use the \helpref{\_()}{underscore} and 
+\helpref{wxPLURAL}{wxplural} macro for all literal strings.
