Character Encoding Detection and Conversion Module

This module provides robust character encoding detection and conversion capabilities to handle the diverse encoding scenarios found in real-world PDF files.

Overview

Many PDFs contain text encoded in various character sets beyond UTF-8, including:

• Latin-1 (ISO 8859-1) - Common in European documents
• Windows-1252 - Microsoft’s extension of Latin-1
• MacRoman - Apple’s legacy encoding
• Various PDF-specific encodings

This module provides automatic detection and graceful conversion with fallback handling for unrecognized characters.
