Specifically, scroll down to section 8.4 and take a look at the table they've got there. Notice anything wrong?
I don't think that bytes 8 through 2048 are really (Reserved for future standardisation). I think someone copy-pasted the table from the section before and didn't erase the last entry.
What do you think? I've emailed the ECMA helpdesk to see if they can help me out.
Edit: They just got back to me, and agree with my conclusion. I found an error in an ECMA standard! [grin]
