MJcdi - Bijoy ANSI ⇄ Unicode PDF Converter [β]

MJcdi is a barebones node.js CLI tool that converts Bangla text inside PDFs between Bijoy ANSI encoding and Unicode using greedy substitution and PDF text extraction.

⚠️ Status: Beta. Still in active development.
Currently designed as a bare minimal CLI requiring manual node.js installation.

Features

• Convert digital Bijoy (ANSI) text in PDFs to Unicode
• Supports reverse*: Unicode → Bijoy (*festered with bugs and won't be worked on, cause MJcdi.)
• Greedy substitution with post-processing reordering
• ⚠️ Known issue: Repha (র্) in tri-, tetra- and penta-consonantal conjuncts. e.g.,
  • tri: বজ্র্য instead of বর্জ্য
  • tetra: আক্ষ্র্য instead of আর্ক্ষ্য
  • penta: কাৎর্স্ন্য/কাত্স্ন্র্য instead of কার্ৎস্ন্য/কার্ত্স্ন্য
• PDF input → .txt output

Requirements

• node.js (v14+ recommended)
• npm (comes bundled with node.js)
