Examples

Decoder

import { MUTF8TextDecoder } from "@kokiri/modified-utf8";
import { assertEquals } from "@std/assert";

const dec = new MUTF8TextDecoder();
assertEquals(
  dec.decode(new Uint8Array([0x68, 0x65, 0x6C, 0x6C, 0x6F])),
  "hello",
);

assertEquals(
  dec.decode(new Uint8Array([0xC0, 0x80, 0xE2, 0x98, 0x83])),
  "\u0000☃",
);

Encoder

import { MUTF8TextEncoder } from "@kokiri/modified-utf8";
import { assertEquals } from "@std/assert";

const enc = new MUTF8TextEncoder();
assertEquals(
  enc.encode("hi"),
  new Uint8Array([0x68, 0x69]),
);

const dest = new Uint8Array(5);
const { read, written } = enc.encodeInto("\u0000☃", dest);
assertEquals(read, 2);
assertEquals(written, 5);
assertEquals(dest, new Uint8Array([0xC0,0x80,0xE2,0x98,0x83]));
