With these caveats, it is certainly acceptable.

But I still do not like it, because I can not help but think people who want
that option are using the API incorrectly. Supporting invalid uses now may
be a burden later.

I did not think of cross-compilation. That is a problem indeed.

Then I suspect the best course of action is to provide in lavu a simple API
on top of either iconv/libiconv or a native recoding implementation
supporting only the really easy and necessary encodings (UTF-8, ISO-8859-1
and UTF-16). And possibly add later support for other libraries than iconv,
if they exist.
