So, I changed a smart quotes setting for single quotes, to make ‘quoted words’ look like ‹quoted words›. Not sure I’m going to keep that (it used to be a ‘thing’ in science fiction to use odd quote marks, not so much any more), but it showed me something interesting.
However, now when I type an apostrophized word like “doesn’t,” which should not be “smart quoted,” Scrivener replaces the single apostrophe with a “›”. I’m pretty sure it should not do that. If I were using single quotes as single quotes, it’s an unnoticeable issue.
Mucking with smart quote functions, though, might be beyond the scope of Scrivener bug fixes. It is a bug, however.
