Bengali (Bangla) is the 7th most spoken language globally with over 230 million speakers. Yet the tooling available for professional Bengali text handling has always lagged behind. Today I want to share a project aimed at fixing that: UnicodeToBijoy.net.
The Problem: Unicode vs Bijoy Encoding
If you've ever worked with Bengali typography, you know the pain. Modern devices output text in Unicode (UTF-8), but the professional design and print industry in Bangladesh still relies heavily on Bijoy (SutonnyMJ) fonts. Copy-pasting between these two systems results in broken characters and corrupted ligatures.
Our converter solves this with a specialized mapping engine that handles all 300+ Bengali conjuncts accurately.
What We Built
- Unicode ↔ Bijoy Text Converter The core engine. It performs bidirectional conversion between modern Unicode and legacy SutonnyMJ encoding. The algorithm processes complex consonant clusters (যুক্তাক্ষর) without any character loss.
Key technical highlights:
Client-side processing (zero server storage)
Handles bulk text (10,000+ words) without lag
Supports Avro phonetic input conversion
- Online Keyboard Tester A browser-based hardware diagnostic tool. It renders a virtual keyboard and highlights each physical key press in real-time. Useful for detecting dead switches, ghosting, and N-key rollover issues.
Use cases:
QA testing for peripheral manufacturers
Gamers checking multi-key registration
General troubleshooting before buying a replacement
Mouse Button Tester
Similar to the keyboard tool, this utility tests left/right/middle clicks and scroll wheel responsiveness. It also includes a double-click speed detector to identify chattering issues in aging mice.Bengali Typing Speed Test
A training and assessment module that measures WPM (Words Per Minute) and keystroke accuracy for Bengali text. This is particularly valuable for users preparing for government data entry exams in Bangladesh.
Features:
Real-time WPM and accuracy tracking
Multiple difficulty levels
Error highlighting for targeted practice
Image to Text - Bengali OCR
An OCR module specifically optimized for the Bengali script. It can extract text from photographs, scanned documents, and screenshots. The output is in Unicode format, which can then be converted to Bijoy using our main converter if needed.English to Bengali Date Converter
Converts Gregorian calendar dates to the official Bangabda (Bengali calendar) system. Essential for formal documentation and cultural references.
Privacy and Security
All text processing happens client-side. We never store, log, or transmit user data to any external server. This makes the platform suitable for handling sensitive corporate and personal documents.
Tech Stack
The platform is built with a modern, lightweight tech stack optimized for speed:
Frontend rendering with minimal dependencies
Optimized for mobile and low-bandwidth connections
SEO-friendly architecture with proper meta tags and structured data
