Hi Ignacio,

Thanks for your feedback!

Yep, the sentence is not really accurate. Will it be better as "it is 
immutable and *can not be indexed properly"?
*

And a better example to expose it:

'sur' at: 3 $r
'sûr' at: 3 $^ (unicode code point value 770)

Advice please, so I can update the book accordingly.

Is your host a Mac, I guess so as mentioned Cmd.

Could be an issue related to the VM. Om my Linux box with an us 
international keyboard, I can comment chunk of code with the keyboard 
combinaision Ctrl-Alt-Shift-["] (on my setup I have to do Alt-Shift to 
access directly the " character, otherwise it will try to compose with 
other character latter on.

May be take a look at your VM options.
