[Actually downloaded from <https://github.com/pdf-association/pdf20examples/raw/master/pdf20-utf8-test.pdf>](https://github.com/mozilla/pdf.js/files/7871477/pdf20-utf8-test.pdf)


Configuration:
- Web browser and its version: _Firefox 96_.
- Operating system and its version: _Windows 7_.
- PDF.js version: the one that comes with _Firefox 96_.
- Is a browser extension: I think so.

Steps to reproduce the problem:
1. Open the file metadata, bookmarks and layers are displayed wrong.
2. The explanation on how this works for PDF-2 seems to be https://www.pdfa.org/understanding-utf-8-in-pdf-2-0/. 

What is the expected behavior? (add screenshot)

Right character display.
