@ -114,12 +114,8 @@ Non-doc comments are interpreted as a form of whitespace.
## Whitespace
Whitespace is any non-empty string containing only the following characters:
- `U+0020` (space, `' '`)
- `U+0009` (tab, `'\t'`)
- `U+000A` (LF, `'\n'`)
- `U+000D` (CR, `'\r'`)
Whitespace is any non-empty string containing only characters that have the
`Pattern_White_Space` Unicode property.
Rust is a "free-form" language, meaning that all forms of whitespace serve only
to separate _tokens_ in the grammar, and have no semantic significance.
