Sto cercando di migliorare il mio blog (su piattaforma wordpress) in modo che sia visibile ANCHE con cellulari e i-phone e per ciò sto testando il blog con http://ready.mobi (che mi hanno consigliato qui sul forum) in cui mi da diversi errori tra cui quello sottostante.
Volevo capire come fare le modifiche senza sballare il blog... grazie!

sono confusa tra iso e utf!!!! aiuto! come devo fare?

codice:
Correct character encoding is essential to ensure that pages render correctly on devices. Different character encodings are required for different document types. XML documents should always have a UTF-8 character set. Documents that are served as MIME type text/html should be encoded in ISO 8859-1.

The following line shows how to set correct encoding in an XML document:

<?xml version='1.0' encoding='UTF-8' ?>

Make sure you specify the correct character encoding for your pages. If you do not specify the correct character encoding then your page may display with strange characters. We strongly recommend the use of utf-8 encoding for maximum compatibility.

Pages delivered with the text/html MIME type are assumed, by default, to be encoded using ISO-8859-1. If you are using text/html and delivering utf-8 you must set the HTTP Content-Type header to say so.

If you are developing your Web pages in a Windows environment you should note that the default character encoding is often Windows CP 1252 - which is similar to, but not identical to ISO-8859-1.
