Convert CID to PFB

The CID (Character Identifier) file extension, developed by Adobe, is used for CID-keyed fonts, which are composite (multibyte) Type 1 fonts designed to support large character sets, particularly for East Asian languages like Chinese, Japanese, and Korean. These fonts address glyphs by number rather than name, allowing for efficient handling of extensive character sets. Introduced to meet the demands of the Far East markets, CID fonts facilitate high-quality digital typesetting and printing by leveraging the PostScript language.

The PFB (Printer Font Binary) file extension is associated with Adobe's Type 1 fonts, primarily used in Windows operating systems. These files store font data in a compact binary format, which includes glyph data and encryption for protection. Introduced in the 1980s, PFB files were part of Adobe's PostScript technology, enabling high-quality digital typesetting. They work alongside PFM (Printer Font Metrics) files, which contain character measurements. PFB files are essential for precise font rendering in professional printing and digital design.
