dxf文件图层名称乱码

[zxh95320]

请问我用C#生成的dxf图层名称(中文)乱码的问题，您有没有思路解决？

`StreamWriter sWriter = new StreamWriter(path);
sWriter.WriteLine("0");
sWriter.WriteLine("SECTION");
sWriter.WriteLine("2");
sWriter.WriteLine("ENTITIES");
sWriter.WriteLine("0");
sWriter.WriteLine("POINT");
sWriter.WriteLine("8");
sWriter.WriteLine("点层", Encoding.UTF8);
sWriter.WriteLine("10");
sWriter.WriteLine(561452.256);
sWriter.WriteLine("20");
sWriter.WriteLine(56235.2356);

                sWriter.WriteLine("0");
                sWriter.WriteLine("TEXT");
                sWriter.WriteLine("8");
               sWriter.WriteLine("注记", Encoding.UTF8);
                sWriter.WriteLine("10");
                sWriter.WriteLine(561452.256);
                sWriter.WriteLine("20");
                sWriter.WriteLine(56235.2356);
                sWriter.WriteLine("40");
                sWriter.WriteLine(10);
                sWriter.WriteLine("1");
                sWriter.WriteLine("Q56");
            
            sWriter.WriteLine("0");
            sWriter.WriteLine("ENDSEC");
            sWriter.WriteLine("0");
            sWriter.WriteLine("EOF");
            sWriter.Close();`
