iOS, Xcode - working with international file names in code

I'm using Objective-C and Cocoa Touch framework.

I have few image files in my iPhone application. Some file names are in English and some are in Japanese like "ココ奈ごろにゃんIcon.png"开发者_开发问答.

I'm creating views programatically and not using IB.

My code is not able to read files with name in Japanese language. How can I get this work done?

You should change your source code's encoding to Unicode (UTF-8) or Unicode (UTF-16).

File Inspector -> Text Settings -> Text Encoding
