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.
