(unmaintained, not thoroughly tested)
A regex to match emojis and symbols like ♘♬☾☤♪♇☛☌☧★ which aren't technically emojis. It's based on @mathiasbynens/emoji-regex.
It doesn't count un-emoji-ish symbols like # as emojis (even though they they are technically emojis with a default textual representation according to the spec - read more here: mathiasbynens/emoji-regex#33).
Thanks to @gilmoreorless, it also fixed this issue: mathiasbynens/emoji-regex#28
