How do I recover a file which cannot be opened due to using Japanese characters in the file path? I saved a word document to a path similar to: "something/にほん.docx" then closed down Word as it appeared to save successfully. I looked in Finder and the file wasn't there. I opened Word again, and I can see the file in the "Recent documents" folder but when I try to open it I get "this document is either deleted or not currently accessible". Is there a way to recover it? Obviously I can rename it to something using the roman alphabet. 

Possibly relevant info:


I am on macOS 10.13.1 on a 15 Inch Mid-2015 Retina MacBook Pro.
My Mac system language is English (UK).
I have enabled hidden files in finder.


I have tried:


Using the mv terminal command to rename the file. It says the file cannot be found.
Setting my primary system language to Japanese. Still no sign of the file.


Does anybody have anything else I could try?
I got it. Even though the file didn't appear in the folder, I searched for it within Finder and it came up. Simply renamed it and then opened it in Word normally.
