Especially, it works in graphemes, and ".codes" lets you count 
code points. The article isn't even mentioning "code units".

OTOH, it mentions both graphemes and grapheme clusters, without 
much distinction. So I'm not exactly sure which is the default 
focus.

What distinction is there to be made? As far as I understand, a grapheme 
cluster is a sequence (or cluster) of code points that together 
represent one grapheme.

That's the distinction, yes. The article mentions both in a way 
that makes me unsure if Perl 6 confused the terms (or maybe it's 
just the article that isn't being clear).

But how would you "focus" on one or the other?
Is there any operation that works differently on graphemes than on 
grapheme clusters?
Counting/skipping/extracting graphemes is the same as counting grapheme 
clusters, no?

Eg it says ".chars returns the number of characters (aka 
graphemes)"

Does this count the number of graphemes, or the number of 
grapheme clusters? Later on with \r\n it pretty much says that it 
counts grapheme clusters. Here it says it counts graphemes.

Sorry, I still don't get it. Can you give an example string where 
counting graphemes gives a different result from counting grapheme clusters?

Huh. On researching "grapheme cluster", I see it is a weird 
Unicode term that apparently means the same thing as grapheme. 
Definitely something to avoid in an article (or, explain very 
carefully).
To the uninitiated, "grapheme cluster" means "a cluster of 
graphemes" and implies a one-to-many mapping.
