Terminal control/Display an extended character

From Rosetta Code
Task
Terminal control/Display an extended character
You are encouraged to solve this task according to the task description, using any language you may know.
Task

Display an extended (non ASCII) character onto the terminal.

Specifically, display a   £   (GBP currency sign).

ACL2

(cw "£")

Ada

with Ada.Text_IO; use Ada.Text_IO;
with Ada.Characters.Latin_1;
 
procedure Pound is
begin
Put(Ada.Characters.Latin_1.Pound_Sign);
end Pound;

Ada allows Unicode characters in the source, and provides output functions on "wide characters".

with Ada.Wide_Text_IO; use Ada.Wide_Text_IO;
 
procedure Unicode is
begin
Put("札幌");
end Unicode;

AWK

You can print a literal "£".

BEGIN { print "£" }

You can print a "£" using the escape sequences that match the encoding of your terminal.

cp437 "\234"
iso-8859-1 "\243"
euc-jp "\241\362"
utf-8 "\302\243"
gb18030 "\201\60\204\65"
BEGIN { print "\302\243" } # if your terminal is utf-8

ZX Spectrum Basic

The ZX Spectrum uses a modified ascii character set that has a uk pound sign at character number 96:

10 PRINT CHR$(96);

BBC BASIC

You can print a literal £ if it is available in the default ANSI code page:

      PRINT "£"

But to be on the safe side you can do this:

      VDU 23,22,640;512;8,16,16,128+8 : REM Enable UTF-8 mode
PRINT CHR$(&C2) CHR$(&A3)  : REM UTF-8 encoding for £

bc

You can print a literal "£".

Befunge

There's no portable way to print an extended character in Befunge, since character output will typically use the default code page of the operating system or environment. On Windows this will often be Windows-1252 or ISO-8859-1 for GUI applications and Code page 437 for console applications (but that also likely depends on the OS localisation).

Example output of a pound character in Code page 437:

"| "+,@

Example output of a pound character in ISO-8859-1:

"%~"+,@

C

Translation of: AWK
#include <stdio.h>
 
int
main()
{
puts("£");
puts("\302\243"); /* if your terminal is utf-8 */
return 0;
}

C#

class Program
{
static void Main()
{
System.Console.WriteLine("£");
}
}

Output:

£

C++

#include <iostream>
 
int main()
{
std::cout << static_cast<char>(163); // pound sign
return 0;
}

Clojure

(println "£")

COBOL

Works with: OpenCOBOL
       IDENTIFICATION DIVISION.
PROGRAM-ID. Display-Pound.
 
PROCEDURE DIVISION.
DISPLAY "£"
 
GOBACK
.

Common Lisp

 
(format t "札幌~%")
(format t "~C~%" (code-char #x00A3))
 

D

Assuming unicode support on the terminal

import std.stdio;
 
void main() {
writeln('\u00A3');
}
£

EchoLisp

 
;; simplest
(display "£")
;; unicode character
(display "\u00a3")
;; HTML special character
(display "&pound;")
;; CSS enhancement
(display "£" "color:blue;font-size:2em")
 
Output:

£

Erlang

In Erlang a string is a list of integers. So the list of 196 is £.

Output:
8> Pound = [163].
9> io:fwrite( "~s~n", [Pound] ).
£

Forth

Works with: GNU Forth version 0.7.0

The emerging ANS Forth 20xx standard includes an XCHAR wordset which allows manipulation of non-ASCII character sets such as Unicode.

163 xemit    \ , or
s" £" type

Go

package main
 
import "fmt"
 
func main() {
fmt.Println("£")
}

Haskell

 
module Main where
main = do
putStrLn "£"
putStrLn "札幌"
 

Icon and Unicon

Write a given character number, say '163', using char to convert the integer into a string.

 
procedure main ()
write ("£ " || char (163)) # £
end
 

J

   '£'
£
'札幌'
札幌

Java

import java.io.PrintStream;
import java.io.UnsupportedEncodingException;
 
public class Main
{
public static void main(String[] args) throws UnsupportedEncodingException
{
PrintStream writer = new PrintStream(System.out, true, "UTF-8");
writer.println("£");
writer.println("札幌");
}
}

Kotlin

// version 1.1.2
 
fun main(args:Array<String>) = println("£")

Lasso

stdout(' £ ')

Result:

 £ 

Locomotive Basic

10 PRINT CHR$(163)

Lua

Lua requires an extension module for UTF-8 support. However, the '£' symbol specified for this task is part of extended ASCII (codes 128 - 255) which can be accessed in the same way as normal ASCII.

print(string.char(156))

Mathematica

Perl 6

To demonstrate we're not limited to Latin-1, we'll print the fullwidth variant.

say '£';
say "\x[FFE1]";
say "\c[FULLWIDTH POUND SIGN]";
0xffe1.chr.say;

Phix

On Windows (Linux should be fine), you may need to set the terminal to a truetype font (eg Lucida Console) and the code page to CP_UTF8 (chcp 65001).
See demo\HelloUTF8.exw for a (not very pretty) way to do that programmaticaly.
The following assumes you have done that manually, and saved the source code file in UTF-8 format.

puts(1,"£")

Output:

£

PicoLisp

(prinl (char 26413) (char 24140))  # Sapporo 

Output:

札幌

PL/I

Racket

Seed7

A write

to a console accepts Unicode characters.
$ include "seed7_05.s7i";
include "console.s7i";
 
const proc: main is func
local
var text: console is STD_NULL;
begin
console := open(CONSOLE);
write(console, "£");
# Terminal windows often restore the previous
# content, when a program is terminated. Therefore
# the program waits until Return/Enter is pressed.
readln;
end func;

Sidef

say '£';
say "\x{FFE1}";
say "\N{FULLWIDTH POUND SIGN}";
say 0xffe1.chr;

Tcl

Provided the system encoding has a “£” symbol in it, this works:

puts \u00a3

Tcl can output all unicode characters in the BMP, but only if the consumer of the output (terminal, etc.) is able to understand those characters in its current encoding will the output actually make sense. Strictly, this is not a limitation of Tcl but of the environment in which it is placed.

If you output device support UTF-8 then:
