Unicode to Bijoy Converter

What Bijoy and SutonnyMJ are

Bijoy is a Bengali typing system. In its legacy layout, SutonnyMJ and other “MJ” fonts from Ananda Computers draw Bangla letters over Latin letters and punctuation. The stored characters do not describe the Bengali sounds: a clerk may see a perfectly readable government letter while the underlying text contains keys such as K, v and ©. The font supplies the appearance. Removing that font reveals the keys.

This explains why an office memo copied into Facebook, a website, a phone message or Google Docs can turn into apparently meaningless symbols. Search engines cannot interpret those Latin keys as the Bengali words the writer intended. Converting them creates actual Unicode Bangla characters. The reverse operation is useful too: newspaper composition desks, printing shops and government document templates may still request SutonnyMJ, so students and staff need a way to deliver Unicode writing in that layout.

How to use the two directions

Deliver Unicode writing as Bijoy

1. Start with the selected Unicode → Bijoy tab and insert your Bangla paragraph in the input field.
2. Read the key sequence in the result field. It will resemble Latin text until a receiving application applies SutonnyMJ.
3. Choose Copy for Word and paste into the destination document. Bangla receives SutonnyMJ; English and Latin digits receive Arial. The receiving computer needs its own installed SutonnyMJ font.

Recover Bangla from an older document

1. Select Bijoy → Unicode before inserting legacy text.
2. Copy the passage directly from Word when possible. Its clipboard formatting identifies which portions actually use SutonnyMJ.
3. Inspect the Unicode result, then copy it to your online form or message. A Unicode Bengali font should display it without SutonnyMJ.

For a complete document, choose the Word file control and open a .docx in the required direction. Font recognition limits decoding to SutonnyMJ portions; conversion back to legacy keys sets supported Bengali portions in SutonnyMJ. Keep the source document for comparison. Files saved in the older .doc format must first be resaved through Word as .docx.

Examples you can check in Word

The right column is generated by this converter. Applying SutonnyMJ to those keys should show the word in the left column. No commercial font file is loaded by this page, so the keys are deliberately displayed in a normal monospace font.

Where Bijoy converters go wrong

Substituting each key independently misses the position of vowel marks and the boundaries of conjuncts. These cases explain why a seemingly small difference can alter a name, a heading or an instruction. The correct readings below are computed using the same decoding function as the tool.

Curly apostrophes are decoded as conjunct pieces only immediately after a half form. The closing double quote is a half cha only when followed by a consonant glyph. Elsewhere those characters remain quotes. A short en dash becomes a u sign only immediately after a Bengali consonant. This context protects ordinary Word punctuation without ignoring genuine glyph sequences.

Bijoy key → Unicode character chart

This full chart was checked against SutonnyMJ 1.0, the version Bangla converter sites load as a web font. The code column identifies the stored character, even when two symbols look similar. Notes distinguish half forms, lower attachments, vowels entered before a letter and reph entered after a syllable.

How we checked it, and other MJ fonts

We drew every SutonnyMJ character next to its Bengali reading in the font itself, then tested whole passages and hard words. Where another converter's label disagreed with the glyph the font actually draws, we followed the glyph.

We tested SutonnyMJ. Other MJ fonts, such as SulekhaMJ, often use the same key positions, so you can paste their text to try it; check the result, and if a letter comes out wrong, email the text to hello@kruti-dev-to-unicode.com. Automatic .docx decoding recognizes SutonnyMJ alone. Avro output and text entered in Bijoy 2018 Unicode mode are already Unicode and need no legacy decoding. A PDF can expose characters in an order different from the printed page, so its copied text may need manual repair before any converter can reconstruct a word.

If the result looks wrong

Check the active direction before editing the result. A paragraph already written in Unicode triggers a direction notice on the legacy decoding tab. If every word is wrong, inspect the source font in Word. A different Bengali font can look the same on screen and still store its letters on other keys.

If English digits turn into Bengali digits, that English section was interpreted as SutonnyMJ: its ASCII digit positions draw Bengali numerals. Copying formatted text from Word separates other fonts. During Unicode → Bijoy conversion, Latin digits such as 2026 are deliberately excluded from the SutonnyMJ run, even inside a Bangla sentence. Unsupported Bengali letters remain Unicode in Nirmala UI, with a note naming the missing characters.
