delphi页面乱码问题如何解决
delphi 页面是ANSI编码mysql数据库全是utf8 如何使页面和数据库的编码保持一致？ 我在页面添加信息到数据库中的中文显示正常你是指网页上还是Delphi上显示乱码，网页上的话也要设置相应页面为UTF8，
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
如果是DELPHI上要显示uft8的话，取出的内容用函数转换下
function unicode2gb( unicodestr:string):string;
var
SourceLength:integer;
DoneLength:integer;
AscNo:integer;
Byte1,Byte2,Byte3:integer;
GbStr:string;
begin
result:='';
if Trim(unicodestr)='' then exit;
SourceLength:=Length(UnicodeStr);
DoneLength:=1;
repeat
AscNo:=ord(UnicodeStr);
case (AscNo and $E0) of
$E0:begin
Byte1:=(AscNo and $0f) shl 12;
Inc(DoneLength);
if DoneLength>SourceLength then break;
AscNo:=ord(UnicodeStr);
Byte2:=(AscNo and $3f) shl 6;
Inc(DoneLength);
if DoneLength>SourceLength then break;
AscNo:=ord(UnicodeStr);
Byte3:=AscNo and $3f;
end;
$C0:begin
Byte1:=(AscNo and $1f) shl 6;
Inc(DoneLength);
if DoneLength>SourceLength then break;
AscNo:=ord(UnicodeStr);
Byte2:=(AscNo and $3f);
Byte3:=0;
end;
0..$bf:begin
Byte1:=AscNo;
Byte2:=0;
Byte3:=0;
end;
end;//case;
GbStr:=GBStr+widechar(Byte1+Byte2+Byte3);
Inc(DoneLength);
if DoneLength>SourceLength then break;
until DoneLength>SourceLength;
result:=GbStr;
end;
不麻烦呀，函数你复制我上面写的这个就行了。你输出时调用下就行了。比如你Delphi上定义两变量，s1,s2;取的内容先放到一个变量s1上，显示时输出S2,用我的函数调用下就行了，
var
s1,s2 : string;
begin
s2 := unicode2gb(s1);
end;
