The unified diacritical characters and unified punctuation characters frequently have the "common" or "inherited" script property. However, the individual scripts often have their own punctuation and diacritics, so that many scripts include not only letters, but also [[diacritic]] and other marks, punctuation, numerals and even their own idiosyncratic symbols and space characters.
