Delphi – unicode & special characters in delphi 2009

delphidelphi-2009

our delphi win32 app uses special characters like micro and copyright. we mostly use the arial. before delphi 2009, we had to provide a way to prevent the micro character from displaying since for some (many/most?) parts of the world, it was not displayed correctly. we'd replace micro with u, copyright with (C)…

now that we're in delphi 2009, can we leave out this option and display the micro & copyright symbols without needing to do this translation.

it would seem to me that this should work everywhere now without this lame replacement scheme now that our app is in unicode.

thank you!

Yes, as long as you're using Unicode strings and not ANSI strings, you can put in whatever extended characters you'd like, and they'll show up properly as long as the font you're displaying in supports them.

Delphi 2009 + Unicode + Char-size

With Unicode SizeOf(SomeChar) <> Length(SomeChar). Essentially the length of a string is less then the sum of the size of its chars. As long as you don't assume SizeOf(Char) = 1, or SizeOf(SomeString[x]) = 1 (since both are FALSE now) or try to interchange bytes with chars, then you shouldn't have any trouble. Any place you are doing something creative stuffing Bytes into Chars or Strings, then you will need to use AnsiString.

(SizeOf(SomeString) is still 4 no matter the length since it is essentially a pointer with some compiler magic.)

Delphi – Unicode Console Application in Delphi 2009

I'm not sure that is what you're after, but you can create Unicode console applications in all 32-bit Delphi versions by using the Windows API functions. I just tried with Delphi 4:

program test;

{$APPTYPE CONSOLE}

uses
  Windows;

var
  s: WideString;
  i: integer;
  Written: Cardinal;
begin
  SetLength(s, 80);
  for i := 1 to 80 do
    s[i] := WideChar(48 + i);
  WriteConsoleW(GetStdHandle(STD_OUTPUT_HANDLE), PWideChar(s), 80, Written,
    nil);
end.

I don't have Delphi 2009 to try how entering Unicode strings in the editor works...
