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');

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"
