A little change inside the function also must be made to make it work:
The line with htoi2 need a little change, the complete code is this:
function UrlDecode(const S : AnsiString; SrcCodePage: Cardinal = CP_ACP;
DetectUtf8: Boolean = TRUE) : String;
var
I, J, L : Integer;
U8Str : AnsiString;
Ch : AnsiChar;
begin
L := Length(S);
SetLength(U8Str, L);
I := 1;
J := 0;
while (I <= L) and (S[I] <> '&') do begin
Ch := AnsiChar(S[I]);
if Ch = '%' then begin
Ch := AnsiChar(htoi2(PAnsiChar(@S[I + 1])));
Inc(I, 2);
end
else if Ch = '+' then
Ch := ' ';
Inc(J);
U8Str[J] := Ch;
Inc(I);
end;
SetLength(U8Str, J);
if (SrcCodePage = CP_UTF8) or (DetectUtf8 and IsUtf8Valid(U8Str)) then
{$IFDEF COMPILER12_UP}
Result := Utf8ToStringW(U8Str)
else
Result := AnsiToUnicode(U8Str, SrcCodePage);
{$ELSE}
Result := Utf8ToStringA(U8Str)
else
Result := U8Str;
{$ENDIF}
end;

Subject: [twsocket] Found a bug and made a fix in function UrlDecode
Proposal to a fix on bug in UrlDecode in OverbyteIcsUrl.pas and
OverbyteIcsHttpSrv.pas.
When calling the function like this:
Memo2->Text = UrlDecode("Ã...ge",CP_ACP,false); // Ã...ge is
Memo2->UTF8encoding of Åge
The resulting text in Memo2 is "Ã&ge" and is impossible to UTF8-dekode back to
the original text.
The fix is to change this:
function UrlDecode(const S : String; SrcCodePage: Cardinal = CP_ACP;
DetectUtf8: Boolean = TRUE) : String;
To this:
function UrlDecode(const S : AnsiString; SrcCodePage: Cardinal = CP_ACP;
DetectUtf8: Boolean = TRUE) : String;
Anyone have any comment on this fix?
Regards Bjørnar
