prompter: Other than the characters you listed, what can \s match?
assistant: In addition to matching the whitespace characters like space, tab, and newline, the `\s` character class in regular expressions can also match other Unicode whitespace characters. These may include characters like the non-breaking space, the em space, the en space, and various other space-like characters in different languages and writing systems.
