Convert cid to cff

What is the difference between .cid and .cff?

Description: 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.; The Common File Format (CFF) is a standardized file structure designed to facilitate the sharing, exchange, and preservation of data across various platforms and applications. It is not tied to a specific domain but is rather a generic format that can be adopted by different types of software and systems for a wide range of data types. The CFF aims to provide a common framework that ensures data interoperability and accessibility, making it easier for users to work with data across different tools without the need for extensive conversions.
