Don't recover lifetimes/labels containing emojis as character literals
Note that at the time of this commit, `unic-emoji-char` seems to have data tables only up to Unicode 5.0, but Unicode is already newer than this. A newer emoji such as `🥺` will not be recognized as an emoji but older emojis such as `🐱` will.
