Convert text to outlines (vectors) in your final design software before exporting if you don't need the text to be live for the final output. They are common in documents utilizing: East Asian

CID-keyed fonts (CIDFonts) were created to handle large character sets—especially for East Asian languages—efficiently within PostScript and PDF workflows. This paper examines six CID font families (cidfontf1–cidfontf6), summarizes their historical design goals, and documents recent updates affecting encoding, compatibility, and performance. The aim is to provide a practical resource for font engineers, PDF tool developers, and typesetters.
