We recently imported the Unicode data files from the latest version
9.0.0 of the standard, perhaps something went wrong with the build
following that?

The completion on character names doesn't use
describe-char-unicodedata-file at all, AFAIK, only the internal
database loaded from uni-*.el files, so I'm guessing that steps 1 and
2 were those which fixed the problem.

Btw, there's no need to point describe-char-unicodedata-file at any
file, Emacs has all that data in its own databases.  And if you are
tracking the master branch, the Unicode database we have there should
always be the latest one anyway.
