To correctly render Khmer script, you must use a library that supports (integrating characters into correct glyph sequences) and embed a compatible Khmer font. Using fpdf2 (Recommended)
Make sure you have a Khmer Unicode font downloaded locally (such as KhmerOS_battambang.ttf ).
import pdfplumber def extract_khmer_text(pdf_path): with pdfplumber.open(pdf_path) as pdf: for i, page in enumerate(pdf.pages): text = page.extract_text(layout=True) print(f"--- Page i+1 ---") print(text) extract_khmer_text("khmer_verified.pdf") Use code with caution. 3. Verification and Troubleshooting Checklist python khmer pdf verified
is a popular fork of PyFPDF. It supports UTF-8 TrueType font embedding for "almost any other language in the world," but historically, it has had issues specifically with Khmer text shaping.
(signing). Below is a technical report on the most reliable methods to achieve this. 1. Reliable Khmer PDF Generation To correctly render Khmer script, you must use
from khmerdocparser import Parser import pdfplumber
Once the text is extracted, it often needs to be normalized and analyzed. The khmereasytools library is "a simple, self-contained library for Khmer text processing, with optional OCR and POS tagging support". For document alignment and data entry workflows, autocrop_kh can be used for "automatic document segmentation and cropping, with a focus on Khmer IDs, Passport and other documents" using a DeepLabV3 model. The broader ecosystem of Khmer language resources, compiled in the awesome-khmer-language repository, includes tools for normalization and word segmentation. (signing)
Extracting text from a PDF without using PyPDF2 : r/learnpython
If you choose fpdf2 , you need to enable text shaping explicitly:
: Digital signing for "verified" status can be handled by libraries like pyHanko or Endesive. Sample Code (FPDF2)
