Scrivener breaks file links with em-dash in filename

Some of my folders on my harddrive have em-dashes in their names. When I drop a link to documents in these folders into Scrivener, the link initially works. Soon enough, the em-dash seems to get replaced by a question mark, and the link breaks.

An example of why using things like em-dashes in filenames is bad practice, perhaps, but Scrivener is the only program I use that can’t handle them.
