The reason I suggested `c > 0x20` instead of `c >= 0x20` is that the space 
character is invisible.
Suggestion:

        return c > 0x20 && c <= 0x7E ?
            Character.toString(c) :
            String.format(Locale.ROOT, "\\u%04X", (int) c);


or
Suggestion:

        return c >= 0x21 && c <= 0x7E ?
            Character.toString(c) :
            String.format(Locale.ROOT, "\\u%04X", (int) c);
