3Extended grapheme clusters (UAX #29, Unicode 17), the same boundaries as Rust's unicode-segmentation 1.13.

5Part of the C port of [alpha-rust-mesh](https://github.com/rsafier/alpha-rust-mesh)'s `mesh-top`, a
6terminal UI built with ratatui: these packages reproduce what ratatui and its Unicode crates compute,
7so a frame drawn in C is the same, cell for cell, as the Rust one.
