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

The ZX Spectrum uses a modified ascii character set that has a uk pound sign at character number 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:
"%~"+,@

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

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.

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.

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.
