(encoding): problem with utf-8 names on mobile devices with Google Drive or iCloud (copy from https://issues.apache.org/jira/browse/CB-14180)

Hallo guys!

maybe this is duplicate, but I can't find other ticket...

I have problem with mobile devices and external storages, like Google Drive.

if I select file with UTF-8 characters, then the plugin can't read this file.

I try to upload files like:

`Bösefile.jpg` (without empty space)
`Böse file.jpg`
`Копия Böse file.jpg`
`Копия "Копия Böse file.jpg"`
etc...
Angular ngf-select plugin show, that the file has always filesize=0 and filename was written broken too. 


If I select file with normal name, then file size was written correct:


same code on desktop app work good.

Has anybody same problem? any "dirty" fix for this? _

*update*

So... I tested on my different apps.
The problem exist if I use `WKWebView`, with normal View work fine...

Would you by any chance have a reproduction case? It would help a lot.

Also, could you please clarify what you mean by "Normal" View, do you mean UIWebView?
I would not expect any behavior difference between UIWebView and WKWebView when it comes to FileSystem since such code resides at the lower WebCore layer.

+Andy / Wenson as I suspect this could be an iOS file picker issue.

I tried:
- On iOS 12 / iPhone, go to http://jsfiddle.net/danialfarid/0mz6ff9o/135/ (sample page relying on ng-file-upload)
- Select an image named 'Bösefile.jpg' from icloud 

-> The image uploaded file and the filename was correct.

I am therefore not able to reproduce the issue.

Having a reproduction case would be extremely helpful here.

I tried the same steps but with Google Drive instead of iCloud and still could not reproduce the issue in MobileSafari.
