Percent-encoding in filenames is not handled correctly:

> echo foo > test%C3%A4test
> curl --upload-file test%C3%A4test https://{redacted}/;echo
https://{redacted}/LN3I1/test%C3%A4test

Loading that URL produces a 404 because the file was actually uploaded as https://{redacted}/LN3l1/test%25C3%25A4test instead, i.e. with the per cent symbols encoded as %25. That's probably the correct way to handle such uploads, but the output of the PUT request should also reflect it.

you're right @JustAnotherArchivist : the current solution was a little clumsy. I fixed with a more straightforward one in #216 , can you give a try?
