[Lazarus] LConvEncoding- why inline func?

[AlexeyT via Lazarus]

procedure InternalUTF8ToCP(const s: string; TargetCodePage: TSystemCodePage;
  SetTargetCodePage: boolean;
  const UTF8CharConvFunc: TUnicodeToCharID;
  out TheResult: RawByteString); inline;
begin
  if not Assigned(UTF8CharConvFunc) then
  begin
    TheResult:=s;
    SetCodePage(TheResult, TargetCodePage, True);
    if not SetTargetCodePage then
      SetCodePage(TheResult, CP_ACP, False);
  end else begin
    TheResult:=UTF8ToSingleByte(s,UTF8CharConvFunc);
    if SetTargetCodePage then
      SetCodePage(TheResult, TargetCodePage, False);
  end;
end;

Func is complex, why it's inline?

It is not supposed to be used directly. It is supposed to be used by a
few other functions, which are called a lot.
