+For some encodings A and B, this function cannot convert directly from A to B,
+although an indirect conversion from A through UTF-8 to B is possible. This
+occurs on some platforms: Solaris 10. --- Gnulib provides a higher-level
+facility @code{striconveh} (a wrapper around @code{iconv}) that deals with
+this problem.
+@item
