They apply to the region between its buffer positions. Which is
usually pretty similar to "characters under the overlay". But
zero-length overlays exist and work, too, and when copying text from a
buffer, overlay properties are not copied as part of the text.
You can even have overlays that are restricted to a single window
displaying the buffer and will not have an effect on other windows
showing the same buffer.
