iText生成pdf处理中文时标点可能会在行首

最终解决办法：

自己要处理的文本采用以下方式处理，因为Paragraph不存在setSplitCharacter ()方法

Chunk chunk = new Chunk(<asian text>,<asian font>);
  chunk.setSplitCharacter(ChineseSplitCharacter.SplitCharacter);
  Paragraph paragraph = new Paragraph(chunk);

然后新建ChineseSplitCharater类，然后就可以使用了。

import com.itextpdf.text.pdf.PdfChunk;
