I know the correct usages but often avoid them as it doesn't confuse the reader, but can break copy/paste usage. I can get by with ASCII hyphen/dash and double-dash for em-dash. I particularly dislike autocorrection of punctuation into more pleasing forms (e.g. smart quotes/apostrophes). This is one reason I tend to do outlining in Github issues more often than G.Docs.

Of course I'm mostly writing about computer/software topics and don't write for publications or a non-technical audience.
