Building a Solution for Bengali Typography: Connecting Legacy Encodings to Unicode

The transition between different text encodings has always been a major pain point for developers and publishers working with the Bengali language. While the entire web runs on standard Unicode, many traditional print media and graphic design tools in Bangladesh still heavily rely on legacy ASCII-based formats like Bijoy Bayanno.

The Problem
When text drafted in legacy fonts is pasted directly onto the web, it turns into unreadable gibberish. Conversely, modern Unicode text breaks when placed into older versions of graphic software like Adobe Illustrator or Photoshop.

The Solution
To solve this persistent issue and bridge the gap for Bengali content creators, I have developed a fast, client-side web utility.

You can try out the live tool here: 👉 http://unicodetobijoy.net/

How It Works
The tool utilizes a highly efficient parsing algorithm that maps complex Bengali conjunct characters (যুক্তাক্ষর) and vowel modifiers point-by-point between the two encoding standards.

Key Features included:

Instant Conversion: Works directly in your browser without communicating with a server, ensuring speed and absolute privacy.
Bi-directional Support: Effortlessly convert Unicode strings back to Bijoy format.
Integrated Avro Keyboard: Type phonetically online in real-time.
Building this tool involved dealing intricately with complex Regular Expressions (Regex) and Bengali grammar rules to ensure 100% accuracy.

I built this tool to be completely free and accessible for everyone—from journalists to web developers. I would love for the Dev.to community to check it out, test the regex logics, and share your feedback on the UI/UX!
