retitle 635382 latex-unicode sources and licensing
severity 635382 serious
Cloning bug to separate the issues.
*New* bug is about the check for pdf mode in ucshyper.sty, and #635382
is about the availability of sources and license of ucshyper.
In the rest of this email, "upstream" is TeX-live, not TeX-live's
upstram for latex-unicode, which I have not identified btw.

Given that the true sources seem to have disappeared, I suppose we
could consider the .sty file to be its own source; it is a stretch,
but removing unicode support for (La)TeX would be rather
... damaging. I really, really vote for that the absolute upper limit
to what we would do about this is we move it to non-free, not remove
(I want good unicode support in my LaTeX!).
Maybe we could ask texlive if they know where to find sources, but I'm
not holding my breath.

Formally even: how do we know we can redistribute it in the way we
