Older CID fonts, widely used in DTP (desktop publishing) software from the late 1990s and early 2000s, are now largely obsolete and unavailable for download. If you encounter a PDF created with such a legacy CID font, you will likely see placeholder names because the original font format is no longer supported or accessible.
In traditional digital fonts, characters are mapped directly to specific keyboard inputs. However, languages with massive character sets—such as Chinese, Japanese, and Korean (CJK)—require tens of thousands of unique glyphs.
Instead of using standard names, every character is assigned a specific "ID" number. Cidfont-f1 F2 F3 F4 F5 F6
Using specialized fonts or subsetted fonts often forces the PDF exporter to create these temporary identifiers.

Unlike standard Western fonts that rely on a 256-character limit (defined by ASCII or ANSI encoding), CID-keyed fonts are designed to support thousands of characters. In a CID system: Search for and download the for your specific

The string "Cidfont-f1 F2 F3 F4 F5 F6" is a technical identifier representing a collection of six CID-keyed font resources within a digital document. It signifies a structure capable of handling large glyph sets—typically for CJK languages—ensuring that complex typography is displayed correctly and consistently across different platforms. For print professionals and software developers, recognizing this string helps in diagnosing font embedding issues or understanding the resource architecture of a PDF file.
