Test case to exercise the different encodings: 1. Create a file "some file#@%M<br>%25 .pdf" 2. Build the extension with `gulp chromium` and load it in Chrome. 3. Go to `chrome://extensions/` and ensure that the "Allow access to file URLs" is disabled. 4. Try to open the file from step 1 in Chrome (maybe reload once). 5. PDF.js should be showing a file chooser button. 6. Click on that button and select a different file. Test: Check that a confirmation dialog pops up that warns about a different file name. Cancel the dialog. 7. Click on the button again and select the original file. Test: Check that the file opens as expected.

So when the extension detects a PDF file, the following page is shown (from #6233):
But the user has no way of allowing this access. There should be some work-around to this problem, even if it is an
<input type=file>to select the file (or a preference to disable interception of local files).The text was updated successfully, but these errors were encountered:
