+/// List of characters that are considered punctuation.

+/// Rust does not contain an `is_punctuation` method on `char`, while it does
+/// support [`is_ascii_alphanumeric`](char::is_ascii_alphanumeric).
+///
+/// `CommonMark` handles attention (emphasis, strong) markers based on what
+/// comes before or after them.
+/// One such difference is if those characters are Unicode punctuation.
