I've also attached a text file. Now we can run the characters through a Java program and mix around with the unicode values to see if there's a valid decryption.
Very good, you've got the case under control, I see.
On a side note, about the last part of the code: X16-84165-01.
It can be seen practically in every friggin' piece of paper and item that comes with the Reach [Any] Edition: The disk, the manual, the case, and almost everything in Halsey's diary (The diary itself and The Spartan Insignia don't bear the code)(Should be noted that the code is not the same, the five digits in the middle vary). At first, I though that it was some kind of Reach code. But when I visited my friend who had just bought himself a new Xbox, I stumbled into the boxes and stuff that came with it. And there, I saw it again: the same kind of code. Here, though, the Code was different, beginning with X14 or X12 or such, but the body was the same. And when I visited a local game store on my way back, I noticed that the same code was found in other games too: ODST, Halo Wars, Alan Wake, Crackdown 2...
All by Microsoft Game studios.
Conclusion: The X-Code is some kind of an arragement system for MS Game Studios. It seems that all items of their games must bear that code. Given the fact that these codes were placed to some of the items quite stealthly (or in a manner to make them look like part of the item itself, not just blatantly label it), this side of the page could be simply to present the code in a 'gentle' way.
Not that it should be translated.
