There have been questions before about the fact that SE sites automatically convert double-hyphens (e.g.
--) in question titles into em-dashes (e.g.
- Don't change double-hyphens in titles into dashes. At least not on StackOverflow
- Fix Markdown/SmartyPants in question titles
I want to know why the conversion is inconsistent, as seen here:
Is this a glitch? Is there some logic behind when the conversion is made and when it isn't? Are there use cases? This just seems odd to me.
