String from filename showing %20 where spaces are in the name, unwanted

Question

I'm bringing in images with names that contain spaces, English names and Chinese names, and using those filenames to create strings that are presented beneath their images.

This worked fine until I started putting Chinese into the image file names.

Now, unfortunately all spaces are coming in as

%20

and an example of Chinese looks like this:

%E7%99%BE%E9%A6%99

I have Chinese Simplified installed, and setup in internalisation settings of the project in Xcode... but somehow I'm missing something. Which isn't the first time, and won't be the last.

What do I need to do to make Unicode work?

With strings like Chinese names, in console usually its represented by unicode characters but properly shown in UI. Please go through below question it may be good place to start http://stackoverflow.com/questions/31272561/working-with-unicode-code-points-in-swift — Dileep, Nov 15 '16 at 18:22
@DILi These are not showing correctly in the app, either. It's not just the console that's a problem, it's an issue with the file name encoding, as per Misha's answer. This isn't strings in a text file or copy-pasted into the app, it's the actual file names of imported image files. As a result, the file names, when grabbed inside the app seem to be coming in encoded with percent encoding. Whatever that is. — Confused, Nov 15 '16 at 18:27

The path is urlencoded if you urldecode the path spaces should turn out fine

For Swift 3:

substring.removingPercentEncoding

For Swift 2.3:

substring.stringByRemovingPercentEncoding

Yes! In answer to my own stupid question. And it returns a String? (optional). Doh! – Confused Nov 15 '16 at 18:24
i think this is your chinese word : 百香 – Misha van Broekhoven Nov 15 '16 at 18:29
Spot on! How did you invert it from percent encoding? – Confused Nov 15 '16 at 18:32
var str = "%E7%99%BE%E9%A6%99" str = str.removingPercentEncoding ?? "" debugPrint(str) – Misha van Broekhoven Nov 15 '16 at 18:36
argh, of course. I'm on an average run for stupid questions. All of them ;) – Confused Nov 15 '16 at 19:02
