Benchmark

Comparison with iconv-lite (operations per second)

chars	tiny-sjis-encoder	iconv-lite	faster
30	1,491,271	789,446	1.89x
300	471,622	222,128	2.12x
3000	61,771	24,708	2.50x

About 2x faster than iconv-lite.

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

Decoder?

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