Fontseal: Glyph Coverage

About

Fontseal is a focused type coverage desk for designers, publishers, and print production. Import a TTF, OTF, TTC, or OTC font from Files. Paste the exact copy you plan to use. Fontseal checks each distinct Unicode scalar in that copy against the selected font face's own nominal character map, then shows the missing codepoints and how often they occur. Edit the copy or choose another face and run the check again. Open a full-size specimen view to inspect the text at different sizes. Save projects locally so you can return to a font and its copy. Share a named PDF coverage proof and a CSV with every checked codepoint. The imported font file is not attached to the export. Fontseal reports nominal Unicode cmap coverage. It does not validate complex shaping, ligatures, visual fallback, print appearance, font licensing, or whether a typeface suits a design. A 100% result is not a production certification. No account, subscription, ads, analytics, tracking, cloud sync, or developer-server upload. Imported font files, copy, and results remain on your device until you delete the project or app.
