The State of CSS 2020. CSS character escape sequences. There are some other cases where you might want or need to escape a character in CSS.
You could be writing a selector for a funky id, class, attribute or attribute value, for example; or maybe you want to insert some weird characters using the content property without changing your CSS file’s character encoding.
