When @code{iconv} encounters an input character that is valid but that
cannot be converted to the output character set, glibc's and GNU libiconv's
@code{iconv} stop the conversion. Some other implementations put an
-implementation-defined character into the output buffer. ---
+implementation-defined character into the output buffer.
Gnulib provides higher-level facilities @code{striconv} and @code{striconveh}
(wrappers around @code{iconv}) that deal with conversion errors in a platform
independent way.
