Does this iterator has same implementations in ICU?

[DamonsJ]

hi, I want to ask a question about this code :

let afnd = s.nfd();
for item in afnd {
       println!("afnd : {:?},{:?}", item.0 , item.1);
 }

what does the second part(item.1) in the item variable means ?
does the iterator has same implementations in ICU?

Thanks!

Hello,

Can you explain what s contains please? nfd() comes from the UnicodeNormalization trait, and returns a Decompositions which implements an Iterator<Item = char>, I don't see any tuple in the equation.

Yeah, I don't understand the issue here.

Which specific ICU are you talking about? ICU normalization is implemented rather differently but it's based on a spec.
