a string containing one emoji has length == 7 in js and 17 in rust as a boundary test

ref hsivonen.fi A string containing one emoji has length == 7 in JS and 17 in Rust 2024-12-30

I read a string containing one emoji has length == 7 in js and 17 in rust as a constraint signal more than novelty. The link is just the anchor; the mechanics are where the leverage is (source).
