Patching needed for UTF-8

I've installed the SquirrelMail 1.4.20 that comes on Ubuntu 10.04 
repositories and I see that, better than editing system's supported 
locales (to work on ISO-xx charsets), an update is needed for the file 
functions/i18n.php

At this moment the major part of languages lack in the 'LOCALE' arrays 
of a UTF value.

For example:
$languages['es_ES']['LOCALE']  = 
array('es_ES.ISO8859-1','es_ES.ISO-8859-1','es_ES');

Better needs to be:
$languages['es_ES']['LOCALE']  = 
array('es_ES.UTF-8','es_ES.ISO8859-1','es_ES.ISO-8859-1','es_ES');

And then works properly with an Unicode environment.
