Convert pfb to cid

What is the difference between .pfb and .cid?

Description: A Printer Font Binary (PFB) file is a type of font file used specifically in the context of Adobe Type 1 fonts. It stores font data in a binary format, which includes the glyph shapes and font metrics necessary for rendering text accurately on screens and in print. The PFB file is typically used in conjunction with a metric file (with an .AFM or .PFM extension) that provides additional layout information. This file format was widely used for high-quality typography on PostScript printers.; This is a format for presenting fonts in PDF files that was initially conceived to store symbols in the Japanese and Chinese languages because it had a 16-bit structure and allowed for more precise adjustment. CID expands the the potential for PostScript by supporting languages that do not have a left-to-right orientation, and by supporting even a vertical mode of orientation.
