(Firefox :: File Handling, defect)

Description

[utf16]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; fr-FR; rv:1.8.1.4) Gecko/20070515 Firefox/2.0 MEGAUPLOAD 1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; fr-FR; rv:1.8.1.4) Gecko/20070515 Firefox/2.0 MEGAUPLOAD 1.0

Firefox does not open files that contain Unicode characters in their paths, unless the file is dragged and dropped or located via the built-in explorer.

Reproducible: Always

Steps to Reproduce:
1. Go to the page http://ja.wikipedia.org/wiki/%CE%93-%E3%82%A2%E3%83%9F%E3%83%8E%E9%85%AA%E9%85%B8,
go to File -> Save as... and save it exactly as it appears named in the program (Γ-アミノ酪酸.html).

OR

Create a text file and name it "Γ-アミノ酪酸.txt".

2. Make the download manager open the file you just saved in Firefox

OR

Locate the file "Γ-アミノ酪酸.txt" in Windows explorer and make it open with Firefox (just don't drag and drop).
Actual Results:  
The following error occurs: "File not found: Firefox cannot locate the file in the following address: /C:/My Documents/G-?????.htm".

Expected Results:  
The file should have opened.

Drag and drop and built-in explorer handle Unicode files flawlessly though.
