如果我在簡體系統中轉出PDF文檔，在繁體系統打開是亂碼，我知道這是字符集的關係。我現在想問的就是，有沒有辦法用Unicode碼轉出，我看過一些日文的fastreport轉PDF檔，不管在什麼環境下都可以正常顯示。請各位幫幫忙。

要这样的话你就自己去修改导出PDF的单元代码，
我的主页上有Fast Report 控件和使用手册：

用FR，唐兄是能手，我这也有个资料，你看看吧

先謝過兩位了，不過我們公司現在用的還是2.5版本的，本來是有打算升級到3.x版本，但由於需要改動的報表太多，所以一直到現在還沒有更新。不知道2.5版本有沒有辦法處理。

用FR導出的PDF始終不如人意,不過我現在找到一個好辦法,那就是安裝PDF打印機
FR3.X
frxreport1.PrintOptions.ShowDialog:=false;
frxreport1.PrintOptions.Printer:='PDF-XChange 2.5';
//指定打印機
frxreport1.PrepareReport(true);
frxreport1.ShowProgress:=false;
frxreport1.Print ;

FR2.5可以這樣(需引用Printers單元)
frReport1.ChangePrinter(Printer.PrinterIndex,Printer.printers.IndexOf('PDF-XChange 2.5'));//设定打印机
FrReport1.PrepareReport;//准备打印
frreport1.ShowProgress:=true;// 显示打印进度
FrReport1.PrintPreparedReport('',1,True,frAll);//打印

安装Acrobat Professional 7.0，就有了一个虚拟的打印机了，打印生成PDF文档，方便得很哦。
