Problem displaying special characters PHP/ajax

[adridder]

Hey ... i'm fetching my database information with php
for example: "m²" or "kint&co"

then retrieving this with a XMLHttpObject request,

and putting it on my page with innerHTML


the result would be

m? and: kint?co

this causes problems all through my site.
whats the reason for this?

You may need to decode the special characters, or change the charset to one that supports these special characters.
