| Warning Message | Meaning | Severity | |----------------|---------|----------| | “Font not embedded” | Font missing from file | Medium | | “Cannot extract embedded font” | Corrupted subset | High | | “Download font substitution will occur continue exclusive” | Exclusive license blocks embedding | Very High | | “Font substituted, document layout may change” | Standard fallback | Low |

  • Log the user's choice (opt-in only) to improve future handling and suggest embedding when recurring substitution is detected.
  • For automated pipelines, enable a policy: auto-embed fonts for high-priority/brand assets; auto-substitute silently for low-priority content.
  • Use a font manager (FontExplorer X, Suitcase Fusion, or Windows Font Viewer) to check the fsType flags. If the flag includes “Restricted License” or “Exclusive,” embedding is legally prohibited.
