Bijoy vs Unicode: What’s the Difference?
Bijoy is a legacy, font-dependent ANSI encoding for Bangla; Unicode is the modern, universal standard. The key difference is simple: Unicode displays correctly on every device, browser, and app without any special font — Bijoy does not.
Key takeaways
- Bijoy is a font-based ANSI system — it needs the SutonnyMJ font to read and is best for legacy print & DTP.
- Unicode is the universal standard — it works on every device, browser, and app with no special font.
- If Bangla text looks like random English letters, it is Bijoy without its font applied — that is the quickest giveaway.
- You can convert Bijoy to Unicode (and back) in seconds, for free, in your browser.
| Feature | Bijoy (ANSI) | Unicode |
|---|---|---|
| Encoding | Font-based ASCII / ANSI mapping | Universal standard (U+0980–U+09FF) |
| Needs a special font | Yes — SutonnyMJ etc. | No |
| Displays everywhere | No | Yes |
| Searchable & copyable | Often breaks | Yes |
| Conjuncts (যুক্তাক্ষর) | Special font codes | Proper code points |
| Best for | Legacy print & DTP | Web, mobile & modern apps |
The same sentence in both encodings
One line of the national anthem, shown as Bijoy (ANSI) and as Unicode — identical meaning, completely different underlying bytes:
| Encoding | The text |
|---|---|
| Bijoy (SutonnyMJ / ANSI) | Avgvi †mvbvi evsjv‡`k |
| Unicode | আমার সোনার বাংলাদেশ |
The Bijoy row only becomes Bangla when the SutonnyMJ font is applied; the Unicode row reads as Bangla anywhere, with no font installed.
What is Bijoy?
Bijoy is a popular Bangla typing system and keyboard layout. It stores text in ANSI encoding, mapping Bangla glyphs onto English byte positions — usually rendered with the SutonnyMJ font. Because the meaning depends on the font, the same bytes look like random English letters without it. Conjuncts (যুক্তাক্ষর) are stored as special pre-built glyph codes.
What is Unicode?
Unicode is the international text-encoding standard. Every Bangla character — vowels, consonants, signs, and conjunct-forming parts — has its own code point in the Bengali block (U+0980–U+09FF), defined by the Unicode Consortium. The text is self-describing, so it renders identically everywhere and stays searchable and copyable.
Why do conjuncts break between the two?
In Bijoy, a conjunct is a single special glyph; in Unicode, it is built from consonant + hasanta (্) + consonant, and some vowel signs (কার) are stored before the consonant visually but after it logically. A good converter rebuilds these and reorders the signs — which is exactly what our tool does automatically.
Which should you use?
Use Unicode for anything modern — websites, social media, Microsoft Word, Google Docs, and mobile. Keep Bijoy only when a legacy print or DTP workflow requires it.
How can you tell which one you have?
- It looks like random English letters (e.g.
Avgvi †mvbvi) — that is Bijoy (ANSI) waiting for the SutonnyMJ font. - It shows boxes (□□□) — it is likely Unicode, but your device is missing a Bangla font. See how to fix Bangla font boxes.
- It reads as Bangla everywhere — on the web, in chat, on your phone — that is Unicode.
FAQ
Is Unicode better than Bijoy?
For almost everything today, yes. Unicode displays correctly on any device or app without a special font, and it is searchable and copyable. Bijoy is mainly kept for legacy print and DTP workflows.
Can Bijoy and Unicode be converted into each other?
Yes. A converter remaps the characters and reorders vowel signs and conjuncts. You can convert Bijoy to Unicode and back at any time.
Why does Bijoy text look like English letters?
Bijoy stores Bangla as ANSI codes on English byte positions, so it only renders as Bangla when a matching font like SutonnyMJ is applied.
Is Bijoy still used in Bangladesh?
Yes — many newspapers, publishers, and print/DTP houses still work in Bijoy (SutonnyMJ) because their layouts were built on it. For websites, mobile, email, and official digital documents, Unicode is the standard.
Do I need to install a font to read Unicode Bangla?
No. Modern operating systems ship with Bangla Unicode fonts, so it renders automatically. If you see boxes (□□□), your device is simply missing a Bangla font — installing one fixes it.
Which is better for printing and DTP?
For traditional print and DTP, Bijoy/SutonnyMJ is still widely used because page-layout software and existing files depend on it. For everything digital, Unicode is better. Many workflows type in Unicode and convert to Bijoy only for the final print stage.
