PostScript Level 2 Advantages over Postsctipt Level1

PostScript Level 2 provides the following improvements over PostScript Level 1.

Composite Fonts: PostScript Level 2 supports character sets larger than 256 characters, unlike in PostScript Level 1. Japanese fonts require character sets larger than 256 characters.
