Rust separates this out; the standard library gives you bytes and Unicode Scalar Values. Grapheme cluster stuff is in a package on Cargo, maintained by the Servo team.

You can iterate over Grapheme clusters using the standard library: https://doc.rust-lang.org/1.3.0/std/str/struct.Graphemes.htm...

Those are unstable docs for 1.3; they don't exist in today's Rust.

If you rely on libraries, there are ICU libraries for C and Java too, see for example http://userguide.icu-project.org/boundaryanalysis

Sounds like Rust follows in the tradition of C. Like you now always hear about hos C has no string type, just a bunch of char, will we hear in the future that, alas, Rust has no native support for grapheme clustering?

The issue is, there's multiple ways to do the clustering, in my understanding. We picked the most core thing to be our most core thing. Text is hard.

Oh I get it didn't want to come across as flippant. Indeed text is hard.
