Inserting unicode characters using vim⌗

Get the unicode hex code off https://nerdfonts.com/cheat-sheet e.g. a full thermometer is f2c7

Edit the file in vim, go into insert mode and then enter u and then the 4 digit hex code.

Make sure you have a font installed that has the extra code points in it so you can see the right character in the file.
