true 'ß' == '\u00DF' true https://stackoverflow.com/questions/9127644 > "ß" character is equivalent to "ss" (used in German, for example), and this is defined so in your Locale (the Locale you are using in your app). https://www.reddit.com/r/javascript/comments/9i455b > When using capital letters, SS has historically stood for ß.
