Hi Alvaro,

You're right. I had some holes in my assignment. Following should fix it.

   0x7F Reservedthis document

Thanks,

Ali:

Hi!

So, you're really only changing the 0x0C - 0xFA range, right?

If my hex is not wrong, you're missing some pieces below: 0x40-0x7F, and 0xC0-0xCF, which I'm assume remain Unassigned, right?

Thanks!

Alvaro.
