When I convert your test.zip to azw3, this is what I end up with:
Code:
<p class="poet">**<sup class="vn" id="v01010002">2</sup>The sons<sup class="fnr"><a class="calibre3" href="part0000.html#fn01010002a">1</a></sup> of Japheth:</p>
CSS:
.poet {
display: block;
text-align: left;
text-indent: -4em;
margin: 0 0 0 4em
}
The asterisks are the unicode nbsps.
I'm not sure why you would end up with a text-indent of 3%.
