To appreciate the superiority of the CID format, it is necessary to understand the limitations of the past. Before the advent of CID (Character Identifier) fonts, digital typography relied heavily on composite fonts and simple encoding schemes. In older systems, each character was often mapped rigidly to a specific code point, and large font files were cumbersome. If a user needed to print a document containing thousands of Chinese or Japanese characters, the system struggled with memory allocation and rendering speed. Furthermore, older formats often required separate files for different styles or weights, leading to fragmentation and compatibility issues. This is where the "F1, F2, F3, F4" references often appear in technical logs; these are not distinct font families themselves, but rather internal identifiers used by the PostScript interpreter or PDF renderer to map specific font objects to the active CID system. cid font f1 f2 f3 f4 better
