What Is SutonnyMJ Font?
SutonnyMJ is the most widely used Bijoy ANSI font for Bangla. It maps Bangla glyphs onto English byte positions, so the text only appears as Bangla when the SutonnyMJ font is installed — otherwise it looks like random English letters.
Key takeaways
- SutonnyMJ is the most common Bijoy ANSI font for Bangla — used heavily in print, newspapers, and DTP.
- It is font-dependent: the text only reads as Bangla where SutonnyMJ is installed; everywhere else it looks like English letters.
- It is a proprietary Bijoy font, not a free Unicode font — we don’t distribute it here.
- For anything digital, convert SutonnyMJ to Unicode so it works everywhere with no font to install.
How SutonnyMJ works
SutonnyMJ is an ANSI font: instead of standard Unicode code points, each Bangla glyph sits on an English character position. So the bytes for “আমার” are really Latin characters that the SutonnyMJ font draws as Bangla. Remove the font and the disguise falls away — you see the underlying English letters. Conjuncts (যুক্তাক্ষর) are stored as special pre-built glyphs.

The same line of the national anthem in SutonnyMJ (ANSI) and in Unicode — identical meaning, completely different bytes:
| Encoding | The text |
|---|---|
| SutonnyMJ (Bijoy / ANSI) | Avgvi †mvbvi evsjv‡`k |
| Unicode | আমার সোনার বাংলাদেশ |
The SutonnyMJ row only becomes Bangla with the font applied; the Unicode row reads as Bangla on any device.
Where is SutonnyMJ used?
SutonnyMJ has been a default Bangla font in Bijoy-based publishing for decades. You still find it across newspaper and magazine layouts, book and poster DTP, and older office documents produced on Bijoy. Because so much legacy material was set in it, converting that text to Unicode is the usual first step before reusing it online.
SutonnyMJ vs Unicode
Unicode gives every Bangla character its own universal code point in the Bengali block (U+0980–U+09FF), so it displays correctly everywhere without any font dependency. That’s why modern web, mobile, and office apps use Unicode. For the full comparison, read Bijoy vs Unicode.
Do you need to download SutonnyMJ?
Usually not. SutonnyMJ is a proprietary font tied to the Bijoy system, so we don’t distribute it — and for everyday digital work you rarely need it. Instead of chasing the font, convert the text to Unicode and display it with a free Unicode font like SolaimanLipi or Kalpurush. See our best Bangla Unicode fonts guide.
How to convert SutonnyMJ to Unicode
Paste your SutonnyMJ text into the SutonnyMJ to Unicode converter (the same as Bijoy to Unicode) and copy the Unicode result — it will then display on any device without SutonnyMJ installed.
FAQ
What is SutonnyMJ?
SutonnyMJ is the most widely used Bijoy ANSI font for Bangla. It maps Bangla glyphs onto English byte positions, so text only displays as Bangla when the font is installed.
Why does SutonnyMJ text look like English letters?
Because it is ANSI-encoded. Without the SutonnyMJ font applied, the underlying English byte values are shown. Converting to Unicode removes this dependency.
Is SutonnyMJ the same as Bijoy?
SutonnyMJ is the font; Bijoy is the typing system/keyboard. They are used together, so “SutonnyMJ to Unicode” and “Bijoy to Unicode” mean the same conversion.
How do I convert SutonnyMJ to Unicode?
Paste the text into a converter and copy the Unicode result. Use the free SutonnyMJ to Unicode converter for this.
Is SutonnyMJ free?
No. SutonnyMJ is a proprietary font tied to the Bijoy system, not a free Unicode font. For a free, universal alternative, use a Bangla Unicode font such as SolaimanLipi or Kalpurush.
Where can I download SutonnyMJ?
It ships with the proprietary Bijoy Bangla software, so we do not distribute it here. For most digital work you do not need it — convert your text to Unicode and use a free Unicode font instead.
Can I use SutonnyMJ on a website?
It is not recommended. ANSI fonts like SutonnyMJ break search, copy-paste, and accessibility on the web. Convert the text to Unicode and use a Unicode web font so it works for every visitor.
