xiaoyubujimo

我用下面的代码向CAD中写入几个文字,输入中文是只能显示'?'请问如何在程序里修改我写的字符的样式啊.比如说修改成'宋体'.请给点简单的示例谢谢.
char * files_wj;
        char Str[132];
        AcGePoint3d point(x_a+width-50,y_a-height,0.0);
   
        if(acedGetString(0,("\n 请输入文字:"),Str)!=RTNORM)
                return;
        AcDbText *ptext=new AcDbText(point,Str,AcDbObjectId::kNull,20,0);
    ptext->setLayer("MYNewLayer");
   
    AcDbBlockTable *pblocKTable;
    acdbHostApplicationServices()->workingDatabase()
                ->getSymbolTable(pblocKTable,AcDb::kForRead);
    AcDbBlockTableRecord *pblocKTableRecord;
    pblocKTable->getAt(ACDB_MODEL_SPACE,pblocKTableRecord,AcDb::kForWrite);
    pblocKTable->close();
    AcDbObjectId plineObjId;
    pblocKTableRecord->appendAcDbEntity(plineObjId,ptext);
    ptext->close();
    pblocKTableRecord->close();
