Special case? Perhaps, but this is relevant to any app that converts dashes, apostrophes and quotes automatically (a standard feature in editors) while also allowing the user to type "normal" dashes and straight quotes in some other way. In general, any app that filters user input in some way needs to distinguish between original user input and the output of the filter. Otherwise, it will re-apply the filter to data which has already been filtered. Yeah, it's possible to hack around the problem, but the most elegant solution would be to have the `InputEvent` itself indicate whether it is issued by the user.
