the real rationale for adding support of ucs-8 to latex2e is its
appearance as default encoding in at least one linux distribution.

i don't believe there's justification for "main line" provision for
all possible unicode encodings in latex: omega is designed for that
sort of thing, and shows every sign of performing.  it would be nice
to do all of them in latex, but it's not the sort of thing tex is good
at, in bulk (imho at least).

i'm concerned about performance, about memory consumption, and so on.
it would be nice to be proved wrong, but we're not there yet.
