说明
pdffonts lists fonts used in PDF documents. It shows font names, types, and embedding status. Embedded fonts are included in the PDF, ensuring consistent display regardless of installed fonts. Non-embedded fonts rely on system fonts, which may cause appearance differences. Subset fonts contain only characters used in the document, reducing file size. Full fonts include all glyphs. Font types include Type 1 (PostScript), TrueType, CID fonts (for Asian languages), and Type 3 (bitmap/user-defined). Unicode mapping indicates whether text can be reliably extracted or searched. Missing Unicode mapping affects copy/paste and accessibility. Page range options examine specific sections without processing the entire document.
