It would also be good to cover names with a literal "%" character in them. Specially a file that literally has "%20" in it name - that looks like it could be a space!
Some name like text%20.txt might make things explode.

A name like dataFromLastMonth?.txt might also make things explode.

With these filename, the file gets downloaded but with different names.

• text%20.txt downloads with name text .txt
• text?.txt downloads with name text_.txt
  I have mentioned this issue in the comment Download result in 404 if file name contains hash(a.k.a. #) (also when using the webdav path)  #10810 (comment)
