If you do specify values inside the Java code, you can use \uXXXX to inside the code to represent the Unicode characters. These can appear anywhere. For instance, the following is valid Java source code:
That's because \u0061 is the Unicode representation of the letter a, and the Unicode translation occurs before compiling. In other words, the compiler turns that cl\u0061ss and replaces it with class.

Somehow I had the impression it should release last autumn. Anyway, it's possible to download both the JRE and JDK.
- Would it be risky to start developing with Java 7 now?
- Are there any known pitfalls?
- What about deploying applications written in Java 7?
Since you're plainly conversant with 6, what was your (or your company's) thinking regarding that?
For personal use: I'd regard any non-beta release as worth downloading.
For production code: Dunno. You might deploy it for non-critical systems first; particularly if you have a system (such as Solaris 10, or some of the latest Linux releases) that allow you to run them in a different VM (OS VM that is).
