Bengali Unicode to Bijoy & Avro Converter

Understand Unicode, Avro and Bijoy text

Modern Bangla text on websites, Android phones, iPhones and most current office software is normally stored as Unicode. Avro is a popular phonetic typing method that produces Unicode Bangla. Traditional Bijoy publishing workflows, however, may use an older ANSI-style glyph encoding in which Latin code points are displayed as Bangla shapes by a specific Bijoy-compatible font. Copying text directly between these systems can therefore produce unreadable characters even though both screens appear to show Bangla.

This converter provides two directions: Unicode (including text typed with Avro) to Bijoy Classic ANSI, and Bijoy ANSI back to Unicode. It uses ordered mappings for letters, vowel signs, digits, punctuation and common conjunct sequences. It also applies reordering rules for pre-base vowel marks so that legacy glyph order can be reconstructed more usefully than with a one-character substitution table.

Why conjuncts need special handling

Bangla যুক্তবর্ণ combine consonants with the virama/hasanta sign. A sequence such as consonant + halant + consonant may have a dedicated legacy glyph or a special key combination in Bijoy. Conversion therefore searches longer known sequences before shorter characters. If a multi-character conjunct were split too early, the output would no longer match the legacy glyph layout.

Unicode stores logical character order while legacy desktop-publishing fonts often store visual or keyboard order. The vowel sign ি, for example, is visually placed before a consonant even though Unicode keeps it logically after the consonant. The converter includes practical reorder passes for these common cases. Very unusual conjuncts, archaic letters and font-specific private mappings should still be verified in the exact target application.

Step-by-step conversion

1. Select Unicode → Bijoy when your source is modern Bangla from Avro, a website, Google Docs or a phone.
2. Paste or type into the left textarea. The output updates automatically.
3. Check character and word counts to ensure the complete text was pasted.
4. Copy the result and paste it into the required Bijoy-compatible software using the correct legacy font.
5. For old Bijoy text, switch to Bijoy → Unicode, paste the ANSI characters and copy the Unicode result.
6. Proofread names, numbers, punctuation and complex যুক্তবর্ণ before publishing or printing.

India and Bangladesh use cases

In Bangladesh, many newspaper archives, composing houses, print shops and older office documents were created with Bijoy-era fonts, while new websites and mobile systems expect Unicode. Converting old copy to Unicode helps search, indexing, accessibility and cross-device display. In West Bengal and other parts of India, Unicode Bangla is common on the web, but legacy DTP files can still appear in publishing exchanges; the reverse conversion can help when a vendor requests a particular old font workflow.

For data migration, keep an untouched copy of the original file. Text conversion does not preserve page layout, font metrics, kerning, line breaks or artwork. If a PDF was created from outlined text, there may be no editable character stream to convert at all.

Character and word counts

The counters are calculated from the text currently shown in each box. A Unicode grapheme can contain multiple code points, so a simple JavaScript character count is best treated as a technical length rather than a count of visible letters. Word count is based on whitespace-separated tokens, which is useful for checking whether an entire paragraph arrived but is not a linguistic analysis of Bangla morphology.
