CID (Character Identifier) fonts are not standard Windows or Mac fonts like Arial or Times New Roman. Instead, they are a special font format developed by Adobe to handle large character sets—specifically for Chinese (Simplified & Traditional), Japanese, and Korean (CJK).

The labels F1, F2, F3, and F4 are not official font names; they are font substitution placeholders. When a PDF or CAD file cannot find the original embedded font, it falls back to generic CID-keyed fonts named "F1" through "F4". Understanding this distinction is critical before you search for a download link.

Ironically, the free Adobe Acrobat Reader DC installs a subset of these CID fonts onto your system. Once installed, the F1-F4 placeholders automatically map to the correct typefaces.
