[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.

Link to a viewer (if hosted on a site other than mozilla.github.io/pdf.js or as Firefox/Chrome extension):

if (!url) {
    return null;
  }
  try {
    if (options && typeof url === "string") {
      
      if (options.addDefaultProtocol && url.startsWith("www.")) {
        const dots = url.match(/\./g);
        
        
        if (dots && dots.length >= 2) {
          url = `http://${url}`;
        }
      }
      
      
      if (options.tryConvertEncoding) {
        try {
          url = stringToUTF8String(url);
        } catch (ex) {}
      }
    }
    const absoluteUrl = baseUrl ? new URL(url, baseUrl) : new URL(url);
    if (_isValidProtocol(absoluteUrl)) {
      return absoluteUrl;
