//! Unicode punctuation classification for emphasis/strong flanking.
//!
//! Rust core has no `char::is_punctuation`, so CommonMark's notion of a
//! "Unicode punctuation character" (the Unicode `P*` and `S*` general
//! categories, per <https://spec.commonmark.org/0.31.2/#unicode-punctuation-character>)
//! is provided here as a generated, sorted table of inclusive code-point
//! ranges. The set is generated from the Unicode Character Database; it is
//! stored as ranges (not a flat list) to stay compact. `no_std`, no
//! allocation, no dependency.

/// Inclusive Unicode code-point ranges in the CommonMark punctuation set,
/// sorted ascending and non-overlapping.
