Puzzled...

So for UTF-16, there must be a BOM. For UTF-16LE and UTF-16BE, there
must not be a BOM. So if we do this:

   $ printf '\xfe\xff\x00\x0a' | iconv -f UTF-16BE -t UTF-16 | xxd -g1
   00000000: ff fe ff fe 0a 00                                ......

What sort of braindamage is this? Fix iconv.

But as I said, I'm not an expert. I just vented my worries that widespread existing practice would be ignored under the excuse "you are the outlier".
