You paste a Bengali paragraph into Facebook, WhatsApp or a website, and instead of বাংলাদেশ you get something like evsjv‡`k. The document looked perfect in Word. Nothing is corrupted. The text was never Unicode in the first place.
This is the most common Bengali text problem, and it has a straightforward fix.
What Bijoy actually stores
Bijoy is a keyboard layout and a family of legacy fonts. SutonnyMJ is the best-known font in that family. Like Kruti Dev for Hindi or Preeti for Nepali, Bijoy fonts are ASCII fonts: the file stores English letters, and the font draws Bengali shapes in their place.
বাংলাদেশ is stored as evsjv‡`k. It looks right only on a computer that has the Bijoy or SutonnyMJ font installed. On Facebook, a phone, Google Docs or a website, the font is missing, so you see the underlying English letters.
That is the whole explanation. The file is fine; the encoding is legacy.
Why Bengali is harder to convert than it looks
If conversion were a simple letter swap, a find-and-replace would work. It does not, and the reason is the shape of Bengali writing.
In Bijoy, the vowel signs ি, ে and ৈ are typed before the consonant they follow in Unicode. The signs ো and ৌ are written in two parts that wrap around the consonant. Many conjuncts have their own dedicated keys as well.
A correct converter has to rebuild each syllable in logical order before the text will render properly in Unicode. A naive replacement leaves vowel signs in the wrong place, which produces Bengali that looks almost right and is wrong in a way that is hard to spot.
This is why you should use a real converter rather than editing the text by hand.
Fix it with the Bijoy to Unicode converter
- Open Bijoy to Unicode.
- Paste the text, or drop in a
.txtfile. - Read the Unicode preview carefully. Check names, numbers and any word with a
িor a two-part vowel sign. - Copy the result and paste it where you need it.
The converter runs on your device. The text is not uploaded, and it works offline once the page has loaded. It also has a loss report for the reverse direction, which flags characters the legacy font cannot show instead of dropping them silently.
If the text is in a Word document with tables, headers or images, use the Word file converter instead. It reads the font of each run, converts only the legacy text, and keeps the layout.
Fixing a Facebook post or a phone message
Social media and messaging apps are where the problem is most visible, and the fix is the same:
- Copy the Bengali text from Word or from the original file.
- Paste it into the converter.
- Copy the Unicode output.
- Paste that into Facebook, WhatsApp or your message.
Do not try to install SutonnyMJ on a phone to make the post readable. System-wide font installation is generally not possible on phones, and even if you could install it, the post would still be stored as English letters. Other people would still see gibberish.
The converted text works for everyone, on every device, without a font.
Keeping the Bijoy keyboard, losing the legacy format
Many Bangladeshi typists learned the Bijoy layout and type quickly on it. That habit is worth keeping. The storage format is not.
The Bijoy keyboard tool lets you press the Bijoy keys you know and get Unicode Bangla as you type. evsjv becomes বাংলা, and you can copy the result anywhere. No Bijoy or SutonnyMJ font is needed.
If you prefer typing by sound, the Bengali typing page converts Romanized Bengali as you press space. It follows familiar conventions: a is the আ sound, a word-final o is the ো sign, and ng gives the ং of বাংলা.
When you still need Bijoy output
Sometimes the destination is not the web. A print shop, a DTP template or an older exam workflow may require SutonnyMJ keystrokes. In that case, write in Unicode and convert at the end with Unicode to Bijoy. Read the loss report before you send the file: it tells you which characters the legacy font cannot represent.
That direction is the one to be careful with. Unicode has more characters than the legacy font, so some text may not survive the round trip.
How to tell what you have
- Text looks like
evsjv‡`korAvwg: it is legacy Bijoy or SutonnyMJ. Convert it. - Text looks like
বাংলা: it is Unicode Bengali read with the wrong encoding. This is a different problem, called mojibake. Re-open the file as UTF-8, or repair it with the fix broken text tool. - Text shows boxes: it is Unicode, but the device has no Bengali font. Choose a font such as Nirmala UI, Vrinda or Noto Sans Bengali.
- Text is already
বাংলাদেশ: it is Unicode. Nothing to do.
If you are not sure which legacy font produced a sample, paste it into the font detector. Bijoy has a distinctive mapping, but very short samples can be ambiguous.
A practical habit
Write in Unicode and use the Bijoy layout only as an input method. When someone sends you a SutonnyMJ file, convert it once and keep the Unicode copy. When a printer insists on Bijoy, convert back at the last step and check the loss report.
That way your Bengali stays readable on phones, searchable on the web, and portable to whatever software comes next, while your fingers keep the layout they already know.
