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.

Specialize a type, not a var.

System codepage

Code: Pascal

[-]
Console output codepage

System codepage
