    public static Parser<Void> isChar(char ch, String name) {
      return isChar(CharPredicates.isChar(ch), name);
    }
docs: A scanner that succeeds and consumes the current character if it is equal to {@code ch}.
  
  @param ch the expected character.
  @param name the name of what's expected logically. Is used in error message.
  @return the scanner.
  @deprecated Use {@link #isChar(char)} instead
  or use {@code Patterns.isChar(ch).toScanner(name)}.
