支持把携带汉字的字符转转化为Byte数组吗？

Question

需要将打印数据转化为ArrayBuffer，但是打印内容携带汉字的话会出现打印汉字乱码，如何解决呢？

口味你好，你可以这样操作一下试试：

// 字节流转成可理解的字符串 
function uint8ArrayToString(array:Uint8Array) { 
  // 将UTF-8编码转换成Unicode编码 
  let out: string = ""; 
  let index: number = 0; 
  let len: number = array.length; 
  while (index < len) { 
    let character = array[index++]; 
    switch(character >> 4) { 
      case 0: 
      case 1: 
      case 2: 
      case 3: 
      case 4: 
      case 5: 
      case 6: 
      case 7: 
        out += String.fromCharCode(character); 
        break; 
      case 12: 
      case 13: 
        out += String.fromCharCode(((character & 0x1F) << 6) | (array[index++] & 0x3F)); 
        break; 
      case 14: 
        out += String.fromCharCode(((character & 0x0F) << 12) | ((array[index++] & 0x3F) << 6) | ((array[index++] & 0x3F) << 0)); 
        break; 
      default: 
        break; 
    } 
  } 
  return out; 
}
