Getting one garbage character from container.exec()

[Akimyou]

const readStream = (stream: stream.Duplex) => {
  let output: string = "";
  return new Promise<string>((resolve, reject) => {
    stream.on("data", (chunk: string) => {
      output += chunk;
    });

    stream.on("end", () => {
     // handle garbage
      resolve(output.trim().split("\n").map(processString).join("\n"));
    });
  });
  
  function processString(str: string): string {
    const out = Buffer.from(str, "binary");
    if (out.readUInt8(0) === 1) {
      return out.toString("utf8", 8);
    } else {
      return out.toString("utf8", 0);
    }
  }
};

May be this function can help you.
