User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36

Steps to reproduce:

Example JSFiddle to reproduce the error:
https://jsfiddle.net/ThomasMichon/hqe0qa8x/
(works in Chrome, not in Firefox)

Create an INPUT element of type="file" and with directory="directory".
Attach a change event listener to the INPUT element, which will read out the list of file names from the HTMLInputElement.files field.

Create a folder on the hard drive named "folder º1". The "º" character is the heart of the issue.
Add a file within the folder named "test.txt". (no special characters)
Click the INPUT element in Firefox.
Select the "folder º1" folder.


Actual results:

The event listener on the INPUT element reads an empty list from the HTMLInputElement.files field.


Expected results:

The event listener on the INPUT element should read the "text.txt" file from the HTMLInputElement.files field.

I can't reproduce it with FF55. Fixed by bug 1331820:

I see you reported the bug against FF55, are you sure? If not, could you update Nighty 55 to the latest build and test again. It should be fixed.

@Loic this is actually against Firefox 52, I just noticed. Apologies for the confusion.

In that case, the bug is already fixed in 54+.
