Speaking of encoding and Firefox, for some reason this piece of crap guesses ISO-8859-1 instead of UTF-8 on your site, @abucci@anthony.buc.ci, even though UTF-8 is specified in the HTML:
Try with the following?
<meta charset="ISO-8859-1">
@abucci@anthony.buc.ci Wow, interesting! I don’t usually have big blocks of comments, so it has never been an issue, but it’s great to know for the next project.
I was gonna say the correct thing to do here normally in most cases is to put the content type encoding in the HTTP response heads
