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

=={{header|AWK}}==
You can print a literal "£".
<syntaxhighlight lang="awk">BEGIN { print "£" }</syntaxhighlight>
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:
<syntaxhighlight lang="basic">10 PRINT CHR$(96);</syntaxhighlight>
=={{header|BBC BASIC}}==
{{works with|BBC BASIC for Windows}}
You can print a literal £ if it is available in the default ANSI code page:
<syntaxhighlight lang="bbcbasic"> PRINT "£"</syntaxhighlight>
But to be on the safe side you can do this:
<syntaxhighlight lang="bbcbasic"> VDU 23,22,640;512;8,16,16,128+8 : REM Enable UTF-8 mode
PRINT CHR$(&C2) CHR$(&A3) : REM UTF-8 encoding for £</syntaxhighlight>
=={{header|bc}}==
You can print a literal "£".
<syntaxhighlight lang="bc">"£
"
quit</syntaxhighlight>
=={{header|beeswax}}==
<syntaxhighlight lang="beeswax">_4~9P.P.M}</syntaxhighlight>
=={{header|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 [[wp:Windows-1252|Windows-1252]] or [[wp:ISO/IEC 8859-1|ISO-8859-1]] for GUI applications and [[wp:Code page 437|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:
<syntaxhighlight lang="befunge">"| "+,@</syntaxhighlight>
Example output of a pound character in ISO-8859-1:
<syntaxhighlight lang="befunge">"%~"+,@</syntaxhighlight>

=={{header|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).<br>
See demo\HelloUTF8.exw for a (not very pretty) way to do that programmaticaly.<br>
The following assumes you have done that manually, and saved the source code file in UTF-8 format.
<!--<syntaxhighlight lang="phix">(phixonline)-->

=={{header|Tcl}}==
Provided the system encoding has a “£” symbol in it, this works:
<syntaxhighlight lang="tcl">puts \u00a3</syntaxhighlight>
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.
