Usage

Browser

<script src="https://cdn.jsdelivr.net/npm/tiny-eucjp-encoder"></script>

ES Modules

import eucjp from 'tiny-eucjp-encoder';

CommonJS

const eucjp = require('tiny-eucjp-encoder');

Encode string to EUC-JP byte array

const bytes = eucjp('Hello 世界');
console.log(bytes); // Uint8Array(10) [72, 101, 108, 108, 111, 32, 192, 164, 179, 166]

Benchmark

Comparison with iconv-lite (operations per second)

| chars | tiny-eucjp-encoder | iconv-lite | faster | |------:|-------------------:|-----------:|-------:| | 30 | 1,052,011 | 284,206 | 3.70x | | 300 | 484,369 | 249,533 | 1.94x | | 3000 | 53,060 | 26,388 | 2.01x |

3.7x faster than iconv-lite for short text, and about 2x faster for longer text.

First call needs a few ms to init. After that, very fast.

Decoder?

const text = new TextDecoder('euc-jp').decode(bytes);
console.log(text); // "Hello 世界"
