Selecting from the CjK languages on the iPhone

Question

I've localized my application in several languages and they all work fine except, I don't know how to test in Chinese. I have made all my .xib files zh for Chinese Simplified but don't know where Chinese is on the iPhone Language settings. I can't tell the difference between Chinese, Korean, Japanese or any other similar far eastern languages therefore, I can't set my simulator or iPhone accordingly to test it. Is there someone who can guide me to the appropriate language setting on the iPhone please?

Answer 1

If you are asking which is which:

繁體中文  - Chinese (Traditional)
简体中文  - Chinese (Simplified)
日本語    - Japanese
한국어     - Korean 

Answer 2

iPhone apps already use UTF-8 by default which is a multi-byte character encoding for UNICODE.

See a nice explanation of this type of encoding here.
