: Download a Khmer Unicode font (e.g., KhmerOS.ttf ). Generate PDF :

df = pd.read_csv('students.csv', encoding='utf-8')

: An alternative that supports over 80 languages and is optimized for deep learning performance. 3. Essential Python Libraries for Khmer Text

If the PDF has no text layer (scanned image), you need OCR (see section 4).
