windows phone8 direct3d的问题 文字，图片，图形的绘制，特别是中文如何处理

Question

小弟有几个windows phone8  d3d的问题，项目挺急的，向大神求救：
第一个问题：文字的绘制，特别是中文如何处理
第二个问题：图片的绘制，最好支持更多的格式，而不仅仅是dds
第三个问题：图形的绘制中的圆石怎么绘制出来
说明：以上的屏幕坐标都以屏幕的左上角为原点，绘制时传入的有关长度的参数采用物理像素
各位大神，本人刚开始做游戏，才接触direct，很生疏，麻烦给个全点的简化demo，不要用d3dxtk这些helper和cocos这些框架，很繁琐看不懂啊，麻烦发到我邮箱一份不胜感激：[e-mail],小弟在此先谢过了

The first question: the rendering of the text, especially the Chinese how to deal with
Second question: drawing pictures, the best support for more formats, not just dds
The third question: the graphics rendering boulders how drawn
Note: The above screen coordinates for the origin to the upper left corner of the screen, the incoming draw length parameters using physical pixels
