Performance Analysis of CID-Keyed Font Subsetting (F1–F7) in PDF Documents Abstract: This paper examines the role of CID fonts labeled F1–F7 as internal PDF font dictionaries. We compare memory usage and rendering speed across free CID fonts (Noto Sans CJK, Source Han Sans) and propose a download strategy for open-source alternatives. Keywords: CID font, F1-F7, PDF font substitution, free font download.

Instead of hunting for broken links to “F1.ttf” (which doesn’t exist in standard TrueType format), download these . Each one replaces the legacy CID function and adds thousands of new characters. This is a specific technical topic related to
If you can share a screenshot of the exact font dialog showing F1–F7, I can tell you the precise original font each corresponds to (based on common Chinese/Japanese printing RIPs). If you can share a screenshot of the
