# base2048 — Binary encoding with Base2048 in Rust.

License: permissive · Maintenance: abandoned · Downloads: 155.3K/mo

## What it is and what it does

Base2048 is a binary encoding library that represents data using Unicode characters from the Basic Multilingual Plane, achieving higher density than Base64 by encoding up to 11 bits per character. It uses a charset free of control sequences, punctuation, quotes, and right-to-left characters, making encoded output displayable on most platforms and compatible with character-counting systems like Twitter and Discord.

The package is implemented in Rust with Python bindings and provides `encode()` and `decode()` functions. It includes detailed error reporting with character positions for decode failures. The main trade-off is that it requires compiled bindings (wheels provided for common platforms) and the project is no longer actively maintained, though the implementation appears stable for the encoding/decoding task it performs.

Use it for:

- Compress data for social media posts where character count matters, such as Twitter or Discord messages.
- Encode binary data into displayable Unicode text for platforms that count characters rather than bytes.
- Replace Base64 when reducing encoded size is critical and Unicode output is acceptable.
- Store or transmit binary data in contexts where the character set must avoid control sequences or RTL characters.
- Implement cross-platform data encoding compatible with the Rust base2048 crate.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Encodes and decodes binary data using Base2048, a character encoding that fits up to 11 bits per Unicode character, reducing encoded size compared to Base64.

Yes, if you need compact Unicode encoding for character-limited platforms and accept the abandoned maintenance status. The package has no runtime dependencies, no known vulnerabilities, and provides a working implementation of a specific encoding task. However, do not use it if you require active maintenance or security updates—it has not been updated since 2022 and the maintainer is no longer active.

## Install

pip install base2048
uv add base2048
poetry add base2048

## Installing base2048

Before you install: Medium install friction due to compiled Rust bindings; wheels provided for common platforms (macOS, Linux x86_64, Windows x64). Package is abandoned as of 1418 days since last release, with no active maintenance.

License in practice: MIT license permits commercial and private use with minimal restrictions; you must include a copy of the license in distributions.

Quickstart:

pip install base2048

import base2048

encoded = base2048.encode(b'Hello!')
# => 'ϓțƘ໐µ'

decoded = base2048.decode(encoded)
# => b'Hello!'

Requires Python 3.7 or later; compiled wheels available for macOS (Intel/ARM), Linux x86_64, and Windows x64—other platforms may require building from source.

Verify before relying:

- Whether the abandoned status affects real-world reliability or if the implementation is considered stable enough for production use.
- Performance characteristics compared to Base64 in typical use cases beyond the emoji compression example.
- Compatibility guarantees with the Rust crate encoding table across future versions.
