As far as I can tell, UWordBoundIndices is just a wrapper around UWordBounds with an identical interface.

In my use case I have a line of text and an index into the .chars() of that string from a mouse double click and I need to obtain the indices of the start and end of the word that enclose that index.

It seemed to me that UWordBoundIndices is what I'd want here, but I don't see how to use it for this purpose. Is this an oversight, or is there a better way to do get the result I'd like?
