Base 2048  

When Base 64 is not enough

Allows up to 11 bits of data per unicode character as counted by social media and chat platforms such as Twitter and Discord.

Uses a limited charset within the Basic Multilingual Plane.

Based on, and uses a compatible encoding table with the Rust crate rust-base2048.

- Charset displayable on most locales and platforms

- No control sequences, punctuation, quotes, or RTL characters

Getting Started

pip install base2048

import base2048

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

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

Up to 2x less counted characters compared to Base 64

import zlib
import base64

import base2048

string = ('🐍 🦀' * 1000 + '🐕' * 1000).encode()
data = zlib.compress(string)

b64_data = base64.b64encode(data)
# => b'eJztxrEJACAQBLBVHNUFBBvr75zvRvgxBEkRSGqvkbozIiIiIiIiIiIiIiIiIiIiIiJf5wAAAABvNbM+EOk='
len(b64_data)
# => 84

b2048_data = base2048.encode(data)
# => 'ը྿Ԧҩ২ŀΏਬйཬΙāಽႩԷ࿋ႬॴŒǔ०яχσǑňॷβǑňॷβǑňॷβǯၰØØÀձӿօĴ༎'
len(b2048_data)
# => 46

unpacked = zlib.decompress(base2048.decode(b2048_data)).decode()
len(unpacked)
# => 4000
unpacked[2000:2002]
# => '🦀🐍'

Decode errors are provided with a character-position of failure

----> base2048.decode('༗ǥԢΝĒϧǰ༎ǥ')

DecodeError: Unexpected character 8: ['ǥ'] after termination sequence 7: ['༎']

• To catch the error, use either base2048.DecodeError or its base exception, ValueError.

import base2048

try:
    base2048.decode('🤔')
except base2048.DecodeError as e:
    print(e)
