Lemmy markdown — which is better than Reddit markdown in some ways, but worse in others — will automatically do a similar conversion, except it takes three hyphens instead of two (two hyphens gets you an en dash). It’s nice, but also unfortunate because it messes up people’s muscle memory since using only two for it mimics what was customary when writing in ASCII, on mechanical typewriters, etc.
An em dash — when used properly — is perfectly fine, but a little academic. iOS will do one automatically with two hyphens and a space.
