01 · About the font
The keyboard and font family that put Bangla on computers in Bangladesh and still drives newspapers, offices and print.
The Bijoy keyboard layout was developed by Mustafa Jabbar, and the first Bijoy software was released for the Macintosh in December 1988 (a Windows version followed in the 1990s). Its fonts, of which SutonnyMJ is the best known, became the usual way to type Bangla for decades. Bijoy fonts are ASCII fonts: the file stores English letters and the font draws Bengali letters.
Bengali makes ASCII encoding unusually awkward. The vowel signs ি, ে and ৈ appear to the left of the consonant but are typed in the same visual order, and ো and ৌ are written in two parts that wrap around it. A converter has to rebuild the correct logical order before Unicode text will render properly.
Today most Bengali text on phones, social media and the web is Unicode. Bijoy remains a typing habit more than a text format: many Bangladeshi typists type with the Bijoy layout, using Bijoy-compatible Unicode keyboards, and still receive or archive documents in SutonnyMJ.

02 · How to
Legacy text only looks like Bengali on a computer that has Bijoy Classic / SutonnyMJ installed. Everywhere else (phones, WhatsApp, websites, search results) it appears as English letters like “evsjv‡`k”. Converting to Unicode fixes that for good.
Pick a Unicode font. Nirmala UI or Vrinda on Windows, Kalpurush or Noto Sans Bengali on the web and in Google Docs.
Have a whole document instead of a paragraph? The Word file converter keeps tables, bold text and layout.
03 · Output font
Unicode text is real Bengali, so any Bengali-capable font will display it. Pick one that looks good for your document.
04 · Mapping chart
This is the actual table the converter uses, generated from the engine. Search for a key you see in garbled text, or for a letter you want to type.

Coverage in this converter
Checked against BanglaKit’s bondhon, the open-source converter this mapping was taken from: 236 of 240 test conversions matched exactly. All 4 differences were errors in that converter. Because the mapping comes from that project, this checks how faithfully it was carried over, not whether the original table is right. See the accuracy page for every difference.
06 · FAQ
Because it was typed in a Bijoy font such as SutonnyMJ, which stores English letters and draws বাংলা only when the font is installed. Converting to Unicode stores the real Bengali characters.
Convert it to Unicode here and paste the result. Those apps can’t display SutonnyMJ, but they display Unicode Bengali on any device.
Yes. Several Unicode keyboards offer the Bijoy layout, and they produce real Unicode text. You only need to convert documents that were typed in the old font.
No. The conversion runs as JavaScript in your browser, so your text never leaves your device. Once the page has loaded, it works offline too.
Nirmala UI or Vrinda on Windows, Kalpurush or Noto Sans Bengali on the web and in Google Docs. Unicode text is not tied to one font, so you can switch typeface later without converting again.
It was checked against the converter its mapping came from: 236 of 240 test conversions matched BanglaKit’s bondhon exactly. Each of the other 4 was reviewed, and every one was an error in that converter. No independent converter has confirmed the table itself yet. The sample on this page converts exactly as expected. No fluent-speaker review has been done, so read important text before you print or submit it.
