In the past, I have used Wikipedia for Unicode to copy — paste. For example, https://en.wikipedia.org/wiki/Em-dash https://en.wikipedia.org/wiki/Em-dash The reason is that it works for many Unicode, I have "w" as a shortcut for Wikipedia search in my browser, and the site will probably be accessible next week/month/year. I won't say Wikipedia won't get ads because they run fund drives all the time...but I turned off javascript for Wikipedia years ago when they added the popup preview on links, so I don't see them on my primary browser.
