TPF is a high volume transaction processing mainframe operating system
TPF's iconv, when present, has already been optimized, but there are limits.
Further performance gains are made using machine / assembly language code
that isn't compatible with iconv.
I think that libcurl is more portable if iconv isn't a requirement, which
might benefit other operating systems in the future.
But the decision isn't mine.
