For OCR support on scanned PDFs:
sudo apt-get install tesseract-ocr-khm # Linux
# or download Khmer trained data for Windows/macOS
khmer_content = extract_khmer_from_pdf('khmer_document.pdf') print(khmer_content[:500]) # First 500 chars python khmer pdf verified
Cause: The PDF viewer lacks a Khmer font.
Verified Fix: In your Python generator, embed the font directly. For OCR support on scanned PDFs: sudo apt-get
# In reportlab - this forces the font into the PDF
pdfmetrics.registerFont(TTFont('KhmerOS', 'KhmerOS.ttf'))
