I sympathize with Jonathan's general concern here -- if this patchset
makes it impossible for people to build documentation with (for example)
their preferred collation order, it would be suboptimal.

On the other hand, this seems to focus on character encodings
specifically; do we really want to encourage any sort of encodings other
than UTF-8?  The only plausible arguments i've heard for documents that
are exclusively CJK characters, which could achieve a modest size
reduction using more targeted encodings.  afaik, there are no such
documents in the kernel, and i doubt there ever will be.
