* ArrayBuffer to String

* var str=Uint8ToString(new Uint8Array(arrayBufferData));

* */

function Uint8ToString(u8a){

var CHUNK_SZ = 0x8000;

var c = [];

for (var i=0; i < u8a.length; i+=CHUNK_SZ) {

c.push(String.fromCharCode.apply(null, u8a.subarray(i, i+CHUNK_SZ)));

}

return c.join("");

}

//fReader.readAsBinaryString(dstring);

//str=fReader.result;

fReader.readAsArrayBuffer(dstring);

var arrayBufferData=fReader.result;

str=Uint8ToString(new Uint8Array(arrayBufferData));

终于完美搞定，你们有用一定要谢我啊。不容易

按字符切片发送就可解决你的问题
