如何使用itextAsian在pdf中编写中文字符

Question

BaseFont.AddToResourceSearch("iTextAsian.dll");
BaseFont.AddToResourceSearch("iTextAsianCmaps.dll"); //"STSong-Light", "UniGB-UCS2-H", 
BaseFont baseFT = BaseFont.CreateFont("STSong-Light", "UniGB-UCS2-H", BaseFont.EMBEDDED);
iTextSharp.text.Font font = new iTextSharp.text.Font(baseFT);

使用此代码我收到错误

  

无法识别带有'UniGB-UCS2-H'的字体'STSong-Light'。
