源代码网整理以下转自大富翁论坛，至于如何重新编译可以参考《Fastreport 3.07 专业的安装及中文化》

源代码网整理以下Q:FastReport 3.x导出PDF乱码怎么解决?(中文乱码,英文没问题).
A:用下面这代码替换 frxPDFFile.pas 中原来的代码就可以了
已在enterprise（应该说是professional） 3.07下测试通过；
注意事项：字体内嵌的复选框不可选。

源代码网整理以下procedure TfrxPDFFont.SaveToStream(Stream: TStream);
var
s: String;
b: TBitmap;
pm: ^OUTLINETEXTMETRIC;
FontName: String;
i: Cardinal;
pfont: PChar;
FirstChar, LastChar : Integer;
MemStream: TMemoryStream;
MemStream1: TMemoryStream;
pwidths: PABC;
Charset: TFontCharSet;

源代码网整理以下 // support DBCS font name encoding
function EncodeFontName(AFontName: String): string;
var
s: string;
Index, Len: Integer;
begin
// Add Begin by ijia 2004.12.20
// 修正在简体系统下繁体字体名的问题
// 只提供 MingLiU, PMingLiU --> 细明体, 新细明体的修正
s:=UpperCase(AFontName);
if Copy(s, 1, 7)="MINGLIU" then
AFontName:="细明体";

if Copy(s, 1, 8)="PMINGLIU" then
AFontName:="新细明体";
// Add end
s := "";
Len := Length(AFontName);
Index := 0;
while Index < Len do
begin
Index := Index 1;
if Byte(AFontName[Index]) > $7F then
s := s "#" IntToHex(Byte(AFontName[Index]), 2)
else
s := s AFontname[Index];
end;
Result := s;
end;

源代码网整理以下begin

s := "";
if fsBold in Font.Style then

源代码网整理以下 Charset := pm.otmTextMetrics.tmCharSet;

if Charset in [CHINESEBIG5_CHARSET, GB2312_CHARSET] then
