According to document:

String conversion assume 8bit characters.

You might need to convert from UTF-8 <-> ASCII.

有试过转换编码么? 按照说明文本, 写入的文字都会使用ASCII, 对UTF-8的文字可能无直接支援

function encode_utf8(s) {
  return unescape(encodeURIComponent(s));
}

function decode_utf8(s) {
  return decodeURIComponent(escape(s));
}
