- * The HTML entities include the non-ASCII Latin-1 characters and

- * The five characters that are ASCII
- * are exported from the `ascii.dart` library.

- * Three names conflict with `ascii.dart`: `$minus`, `$sub` and `$tilde`.
- * If importing both libraries, these three should be hidden from one of the
