Häufige Fehler und Korrekturen
| Symptom | Wahrscheinliche Ursache | Korrektur |
|---|---|---|
| A scanned page produces an empty page marker. | The page contains only an image and no selectable text layer. | Use OCR software; converting the page to an image does not create searchable text. |
| Words appear in an unexpected order. | PDF stores positioned text items rather than a guaranteed semantic reading sequence. | Review multi-column, table, and bidirectional text against the rendered page. |
