yes, that is correct. also Rust's engine matches the full unicode spec as individual characters, whereas .NET's will chop emojis into two sometimes, so Rust at a disadvantage here.

something i've been also wondering is how does Harry (https://ieeexplore.ieee.org/document/10229022) compare to the Teddy algorithm, it's written by some of the same authors - i wonder if it's used in any engines outside of Hyperscan today.
