Hm, is this always true?

For instance, a Shift-JIS document could have redundant shift octets.
(Is that invalid? If so, does an iconv() from Shift-JIS to UTF-8
actually enforce that?) Converting such a document to UTF-8 and back is
presumably not an identity transformation on the octets. If the source
document was not actually in Shift-JIS but was in some other character
set, you could lose data.
