unity UTF8格式加载和保存xml

UTF8格式加载xml

string xmlPath="D:/xxx.xml"
FileLoader fileLoader=new FileLoader();
fileLoader.loadAsync(xmlPath);
fileLoader.onComplete-=onloadXmlComplete;

private void onloadXmlComplete(byte[][] bytesList){
	fileLoader.onComplete-=onloadXmlComplete;
	byte[] bytes=bytesList[0];
	if(bytes!=null){
		string xmlString=System.Text.Encoding.UTF8.GetString(bytes);
		xmlDocument=new XmlDocument();
		xmlDocument.LoadXml(xmlString);
	}
}

UTF8格式保存xml

xmlDocument.Save("D:/xxx.xml");
