Thanks for the pointer to the global Mac OS settings. However, this autocorrect issue has only recently become a problem in Evernote on OSX. I use Evernote to record code and command-line arguments all the time, and I only recently started seeing the smart dash corrections. So, either OSX has changed the default global autocorrect settings, or Evernote has changed the way it conforms to those global settings. If the latter, surely it would be easy to include an option in the Evernote preferences to override autocorrection?
