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.
A WOFF (Web Open Font Format) file is a web font file format used for embedding fonts on websites. It is essentially a compressed version of a font designed to be compact and fast to load, making it highly suitable for use over the internet. WOFF files support metadata and font licensing information, ensuring that fonts can be legally used and distributed. The format is widely supported across modern web browsers, providing a standardized way to include custom fonts in web designs, thus enhancing the visual appearance and typography.
