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

Works with: BBC BASIC for Windows

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>

	return 0;
}

C# 

class Program
{

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

Output:

9> io:fwrite( "~s~n", [Pound] ).

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

jq

Works with: jq

Also works with gojq and with jaq 

"£"

or at the command-line: 

jq -rn '"£"'

or, using the symbol's codepoint: 

jq -nr '[163]|implode'

or: 

jq -nr '"\u00a3"'

Julia

Translation of: C
println("£")
println("\302\243"); # works if your terminal is utf-8

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.

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:

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.
