Yongwei Wu reported a similar problem last week. It appears that
iconv() tries conversion even when there are errors. If you get an
error message when loading the file that should also happen with
iconv().
Although getting an empty string on an error is good to notice something
went wrong, other times you might want to get whatever could be
converted. We could add an argument tells it to fail or do a "best
effort" conversion. I'm not sure that will always be possible, we
depend on what the iconv library does.

definitely have no idea what it is.
