bijoy-to-unicode-file-converter 1.2

Convert your Bijoy (ASCII/ANSI) Bengali text file to Unicode text file easily.

Bijoy to Unicode File Converter

Convert Bijoy (ASCII/ANSI) Bengali text files to Unicode Bangla — a simple, fast Python package.

bijoy-to-unicode-file-converter is a Python library that converts legacy Bijoy / SutonnyMJ / ANSI-encoded Bengali (Bangla) text files into modern Unicode text. If you have old documents typed in Bijoy that show up as garbled characters on the web or in modern apps, this package converts them to clean, portable Unicode Bangla in one function call.

Features

• ✅ Convert an entire Bijoy .txt file to Unicode with a single function call
• ✅ Handles Bengali conjuncts (যুক্তাক্ষর), kars, and reordering rules
• ✅ Skips English lines automatically (language detection) and passes them through unchanged
• ✅ Preserves blank lines and writes clean UTF-8 output
• ✅ Pure Python, lightweight, no heavy dependencies

Installation

pip install bijoy-to-unicode-file-converter

Usage

from bijoy_to_unicode_file_converter import convert_bijoy_to_unicode

# convert_bijoy_to_unicode(input_file, output_file)
convert_bijoy_to_unicode('bijoy.txt', 'unicode.txt')

# bijoy.txt   -> your input file (Bijoy / ANSI encoded Bangla)
# unicode.txt -> the converted Unicode output file (UTF-8)

# Happy Coding!

By default the input file is read as UTF-8. If your Bijoy file uses a different encoding, pass it explicitly:

convert_bijoy_to_unicode('bijoy.txt', 'unicode.txt', encoding='latin-1')

How it works

The converter maps Bijoy ASCII code points to their Unicode Bengali equivalents, then reorders characters (pre-kars, ra-halants, nuktas, and conjuncts) to produce valid Unicode text. Each line is language-checked so English content is left untouched while Bengali content is converted.

Requirements

• Python 3.8+
• langdetect
