[i18n] Problems with charsets

[Alfonso Marí­n Marí­n]

Hello all!

I'm using Spanish translation (es_ES), and when in 
templates/groups/delete.inc, line 10 uses:

<input type="submit" class="button" name="confirm" value="<?php echo 
_("Delete") ?>" />

i get:

<input type="submit" class="button" name="confirm" value="&nbsp;Eliminar&nbsp;" />

Look at those spaces! ¿Why? That causes a malfunction on group delete (in english it works fine, because i get Delete, not &nbsp;Delete&nbsp;)

In es_ES.po: line 2227

msgid "Delete"
msgstr "Eliminar"

There are no spaces.... ¿Local problem or maybe a es_ES compilation problem?

Regards.
Alfonso.
