| Symptom | Likely cause | Fix | |---------|--------------|-----| | Boxes or “□” characters appear | PDF lacks embedded font & system missing Malayalam font | Install a Malayalam Unicode font (Noto Sans Malayalam) and set your reader to use it. | | Text appears reversed or scrambled | PDF uses a legacy encoding (e.g., non‑Unicode “TTF” for Malayalam) | Open the file in → “Convert books” → choose output format PDF → select “Force Unicode” option. | | Reader crashes when opening a large PDF | Insufficient RAM / outdated app | Update the PDF reader to the latest version, or use a lightweight viewer like SumatraPDF. | | No Malayalam titles appear in library app | Library’s catalogue not indexed for Malayalam | Contact the library’s support; many Indian libraries are adding Malayalam collections on request. |
