I do not want to think of where Length, Copy, Delete is good and where UTF8*
needed.
Well, you must think when coding. There is no shortcut. :)
BTW, if you are worried about Delphi compatibility there is now unit
LazUnicode available.
Delphi compatibility not needed for me, but I am a silly coder and don't
understand why the wiki say you can use Length, Copy, Delete with UTF8.
See two examples below. First is a Lazarus project with a simple
editbox, if press á (Alt+160) the form caption show 2. The second
example is a console project (in Lazarus also), if press á (Alt+160)
then Enter see 1 as result. Same FCP same Lazarus. Why is there a
difference in the result?
1.
procedure TForm1.Edit1Change(Sender: TObject);
begin
Caption:=IntToStr(Length(Edit1.Text));
end;
2.
var
s:string;
begin
ReadLn(s);
Write(Length(s));
ReadLn;
end.
