While you cannot download the F1-F3 files directly, you may need the original font that the CID font was supposed to be. If the document was in a CJK language, you may need specialized fonts.
Here, CIDF1 is a placeholder. Look deeper in the PDF streams to find the base font name (e.g., "KozMinPr6N-Regular").

CID (Character Identifier) fonts are a type of font used in PostScript and PDF documents. They are also known as CID-keyed fonts. CID fonts are used to represent glyphs (characters) in a font, and they are commonly used in Asian languages, such as Chinese, Japanese, and Korean.
