Even in his objection Brane said "if this is true". All I (and
Stefan) am saying is we need a more specific objection. If there are
real problems that we cannot resolve, then I am sure we would all be
against this. But we know there are problems with apr_iconv too, so
let's just understand what the problems are.

My knowledge in this area always bounces back and forth. I thought we
were not using apr_iconv on other platforms. Is the issue that we do
use it, but if "iconv" is available that gets used instead?
