feels like many of these characters are Vivaldi. But I can't say which version, or if there is one with alternates that would fit where the standards don't match, or if a secondary font/modifications are going on. perhaps someone more learned can elaborate.

edit -- the "z" actually looks to me like it's been turned upside-down and then had a tail added. The "P" seems like an "R" cut up... not sure about the "T".
