When I open a .dxf document which is from Creo,and in Creo my typeface is "arialuni.ttf" , the chinese text show wrongly .but when I use Creo save this document as a .dwg document ,it show right. and when I use AutoCAD open this .dxf document and save it,then use Driftsight open it again ,the chinese text show right.

If I want driftsight show this .dxf document right directly,I need go to  textstyle and set all the style about chinese style from "@Arial Unicode MS" to "Arial Unicode MS",then the chinese text will show right.

So if I want chinese text show right when I open a .dxf document which need not set anything, how do I do?
