Your console font must support outputting those characters as well.
I got this unit from a discussion on the forum here:
Code: Pascal
[Select]
[+]
[-]
unit
setdefaultcodepages
;
interface
uses
Windows
;
implementation
Const
LF_FACESIZE
=
32
;
Type
CONSOLE_FONT_INFOEX
=
record
cbSize
:
ULONG
;
nFont
:
DWORD
;
dwFontSizeX
:
SHORT
;
dwFontSizeY
:
SHORT
;
FontFamily
:
UINT
;
FontWeight
:
UINT
;
FaceName
:
array
[
0
..
LF_FACESIZE
-
1
]
of
WCHAR
;
end
;
{ Only supported in Vista and onwards!}
function
SetCurrentConsoleFontEx
(
hConsoleOutput
:
HANDLE
;
bMaximumWindow
:
BOOL
;
var
CONSOLE_FONT_INFOEX
)
:
BOOL
;
stdcall
;
external
'kernel32.dll'
name
'SetCurrentConsoleFontEx'
;
var
New_CONSOLE_FONT_INFOEX
:
CONSOLE_FONT_INFOEX
;
initialization
writeln
(
'SetDefaultCodepages unit initialization: DefaultSystemCodePage = '
,
DefaultSystemCodePage
)
;
{$ifdef DisableUTF8RTL}
SetConsoleOutputCP
(
DefaultSystemCodePage
)
;
SetTextCodepage
(
Output
,
DefaultSystemCodePage
)
;
{$else}
SetConsoleOutputCP
(
cp_utf8
)
;
SetTextCodepage
(
Output
,
cp_utf8
)
;
{$endif}
FillChar
(
New_CONSOLE_FONT_INFOEX
,
SizeOf
(
CONSOLE_FONT_INFOEX
)
,
0
)
;
New_CONSOLE_FONT_INFOEX
.
cbSize
:
=
SizeOf
(
CONSOLE_FONT_INFOEX
)
;
// New_CONSOLE_FONT_INFOEX.FaceName := 'Lucida Console';
New_CONSOLE_FONT_INFOEX
.
FaceName
:
=
'Consolas'
;
New_CONSOLE_FONT_INFOEX
.
dwFontSizeX
:
=
8
;
New_CONSOLE_FONT_INFOEX
.
dwFontSizeY
:
=
16
;
SetCurrentConsoleFontEx
(
StdOutputHandle
,
False
,
New_CONSOLE_FONT_INFOEX
)
;
end
.
IIRC that does the trick.

Bart, that's windows centric and not Linux....
Note the code from the question works in my RPi terminal.

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

Code: Pascal

Console output codepage
