The Khmer language (Cambodian) presents unique challenges for digital processing due to its complex Unicode encoding, subscript/subscript character ordering (coeng consonants), and the lack of robust, language-specific PDF validators. This paper presents a Python-based framework for the of Khmer PDF documents. The system integrates three core modules: (1) Structural Integrity (comparing hashed versions to detect tampering), (2) Textual Authenticity (using pypdf and khmer-nlp for glyph-accurate extraction), and (3) Metadata Provenance . We evaluate the framework against 500 real-world Khmer government and educational PDFs. Results show a 99.2% accuracy in detecting altered subscript characters (e.g., ស្រ្តី vs. ស្រី) and a 100% success rate in cryptographic hash verification. Our work provides the first open-source solution for automated Khmer PDF forensics in Python. python khmer pdf verified
