Okay.

In the common case, the failure is not that iconv is broken, but rather
that the string contains a character that cannot be encoded in the
specified encoding.  'scm_encoding_error' raises an exception, which
could be caught and handled by user code.  If uncaught, it would print
an error message that contains only ASCII characters, so should not
fail.

What I suggested was not a workaround, but rather a temporary hack to
debug your problem.

     Thanks,
       Mark
