And what happen if you get rid of all Calibre classes and span?
With something like this (in an epub file):
Code:
<?xml version="1.0" encoding="utf-8" standalone="no"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="it">
<head>
<title></title>
</head>
<body>
<h3>Ciao!</h3>

I work regularly with French files where there are many accents and I don't have problems with Sigil.
