PDF.js stopped working with spaces

[rico666]

Steps to reproduce

1. current nextcloud 20.0.10
2. save some PDF file with space in its name
3. try to look at it.

Expected behaviour

One should see the PDF file

Actual behaviour

error message

PDF.js Version 2.4.456 (build: 228a591c)
Nachricht: Missing PDF "...yaddayadda/Detail%2520some_file.pdf".

-> observe the %2520, in the original file it is a space
when I replace the space with an underscore, all is well.

did work up to now.

confirmed this is persisting and not transient by:

• using with both chromium as well as Firefox and testing with various nextcloud users; Firefox was fresh with clean caches.
• updating the underlying Debian
• rebooting (you could say turning it off and on again)

Problem still there with files that provably worked in a previous version of nextcloud 20.0.7 or so (but not sure about the exact number).

This will be fixed with the next minor releases.
