WXWriteBinFileSync函数返回字符串为空

[dvgco]

SDK-Call-JS-Old.jslib中WXWriteBinFileSync函数返回字符串为JavaScript字符串，未通过stringToUTF8 helper转化，导致C#端接收不到返回值

请问能否提供复现demo，联系研发助手minigamedevop08进行排查

@Oooocean Unity端代码大概这样调用，文件写入正常，result返回值为空。

 ...
 var fs = WeChatWASM.WX.GetFileSystemManager();
 var result = fs.WriteFileSync(filePath, bytes);
 Debug.Assert(result == "ok");

SDK-Call-JS-Old.jslib中函数:

    WXWriteBinFileSync:function(filePath, data, dataLength, encoding){
        return window.WXWASMSDK.WXWriteBinFileSync(
            _WXPointer_stringify_adaptor(filePath),
            HEAPU8.slice(data,dataLength+data),
            _WXPointer_stringify_adaptor(encoding)
        )
    }

调整下即可

    WXWriteBinFileSync:function(filePath, data, dataLength, encoding){
        var returnStr = window.WXWASMSDK.WXWriteBinFileSync(
            _WXPointer_stringify_adaptor(filePath),
            HEAPU8.slice(data, dataLength+data),
            _WXPointer_stringify_adaptor(encoding)
        );
        var bufferSize = lengthBytesUTF8(returnStr) + 1;
        var buffer = _malloc(bufferSize);
        stringToUTF8(returnStr, buffer, bufferSize);
        return buffer;
    }
