While I was searching for something in the Apple docs, I stumble on this:

illegalCharacterSet

Returns a character set containing values in the category of Non-Characters or that have not yet been defined in version 3.2 of the Unicode standard.

On the Unicode website, I find that the latest version is 6.1.0. That's a lot of major versions higher than what Cocoa supports. Does somebody know why Apple doesn't upgrade their framework?

My more important question is: Are there problems for not doing having support for Unicode 3.2+? Will I have problems reading Unicode files created on other systems with a more recent version of Unicode?
