I agree with @azuev-java here, we should focus on the purpose of the API and how this API is supposed to be used.

I think it is reasonable to expect that `Document.getLength()` is a valid index for text APIs, and `getBeforeIndex` should return the last character of the text in this case.

I said it a few times now, _“an index within the text”_ is a vague condition, we should update the specification so that it is clear which indexes are valid.
