To create a swash: type an uppercase letter, then type asterisks until you have achieved the desired length - there are 21 lengths in total for each capital letter!

Note: You need to have ligatures turned on in your chosen program! These swashy uppercase letters are also available as PUA encoded glyphs, so you can use them in any program! More information on that here: https://www.creativefabrica.com/the-ultimate-font-guide/pua-encoded-fonts/
