eww-decode-url-file-name solves a slightly different problem: URLs we
find in Web pages.  There, the encoding is predominantly UTF-8, so we
mainly use that, and fall back to other possibilities as backup.

I believe in the trash case we already know these are file names, so
at least some of what eww-decode-url-file-name does is unnecessary,
IMO.
