      • UnicodeEscaper

        public UnicodeEscaper()
        Constructs a UnicodeEscaper for all characters.
      • UnicodeEscaper

        protected UnicodeEscaper​(int below,
                                 int above,
                                 boolean between)
        Constructs a UnicodeEscaper for the specified range. This is the underlying method for the other constructors/builders. The below and above boundaries are inclusive when between is true and exclusive when it is false.
        Parameters:
        below - int value representing the lowest code point boundary
        above - int value representing the highest code point boundary
        between - whether to escape between the boundaries or outside them
