Step 5: Extracting Text from Khmer PDFs (OCR)

For scanned Khmer documents, standard pdftotext will fail. Use Tesseract OCR with the Khmer language pack: Version: 1

sudo apt install tesseract-ocr tesseract-ocr-khm
# Convert PDF to image, then OCR
pdftoppm scanned.pdf page -png
tesseract page-1.png output -l khm

6. Command-Line Khmer PDF Utilities

• pdftotext (poppler-utils) – Works decently for modern Khmer PDFs.
• pdfgrep – Search Khmer text in PDFs (UTF-8 aware).
• gs (Ghostscript) – Re-process problematic PDFs:

  gs -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -o output.pdf input.pdf
  

Best Option: Okular (KDE)

Okular has superior support for complex text layout (CTL) out of the box.

sudo apt install okular  # Ubuntu/Debian

Open your Khmer PDF, go to Settings > Configure Backend, and ensure "Use smooth text" is disabled for complex scripts.
