Base16384 encoder and decoder

Base16384

A unicode-based encoding scheme that presents binary data (sequence of 8-bit bytes) in sequences of 14-bit printable Chinese characters. It saves 17% space compared to base64.

Inspired by fumiama/base16384.

Description

Base16384 uses 16384 (2¹⁴) Chinese characters (from \u4E00 to \u8DFF) to represent binary data.

If the length of the binary data is not a multiple of 7, we will add a \u3D0x (where x is the remainder modulo 7) after the output.

Comparison

	Base64	Base16384

Usage

import { decode, encode } from 'base16384'

const buffer = encode('Example') // Uint16Array
new TextDecoder().decode(decode(buffer)) // 'Example'

API

encode(data)

• data: string | Uint8Array original binary data
• returns: Uint16Array base16384-encoded data

Encode binary data to base16384.

decode(data)

• data: string | Uint16Array base16384-encoded data
• returns: Uint8Array original binary data

Decode base16384 to binary data.
