It's somewhat confusing as this class adapts `CharacterIterator` into
`CharSequence` which are similar to each other (thus the bug). Those
`beginIndex`/`endIndex` designate the range in the source `CharacterIterator`,
and this `length()` method should return the entire text length of the
`CharSequence` nevertheless, thus it should start from `0` to `endIndex`.
