Inside the middleware method

function sample(ctx) {
  const {name} = ctx.query

  const uint8 = Uint8Array.from([...name].map(c => c.codePointAt(0)))
  const str = new TextDecoder().decode(uint8)

  console.log({uint8, str})
  // => { uint8: Uint8Array(6) [ 237, 149, 156, 234, 184, 128 ], str: '한글' }

  ctx.body = str
}

Hope this helps! 😉

thank you, i solve the problem below code

app.use(async (ctx: Koa.Context, next: Koa.Next) => {
    const query = ctx.query;
    for (const q in query) {
        const queryValue = String(query[q]);
        const queryCodePoint = Uint8Array.from([...queryValue]
            .map(c => Number(c.codePointAt(0))));
        const queryStr = new TextDecoder().decode(queryCodePoint);
        query[q] = queryStr;
    }
    ctx.query = query;
    await next();
})

your code was very helpful!
