+      <item value="The characters of a string. A character is a Unicode Grapheme cluster represented by a substring of the original string. The `Characters` class is an [Iterable] of those strings. However, unlike most iterables, many of the operations are eager. Since the underlying string is known in its entirety, and is known not to change, operations which select a subset of the elements can be computed eagerly, and in that case the operation returns a new `Characters` object. The [iterator] provided by [Characters] is a [CharacterRange] which allows iterating the independent characters in both directions, but which also provides ways to select other ranges of characters in different ways." />
