I got your point now. The spec says that `index an index within the text` and
that means the value should range from 0 to length - 1. And that means,
`getBeforeIndex` won't be able to fetch the last character and `getAfterIndex`
won't be able to fetch the first character.
So, if someone wants to retrieve the first or last character, they shouldn't
rely on `getAfterIndex and getBeforeIndex` method respectively, rather use
`getAtIndex` method to get the first and last character with index passed as 0
and length -1 respectively.
Right ?
