HTML5 does support named entities, however, the epub3 standard does not support them
without additional entity declarations in the doctype, because epub3 content docs (=HTML files) need to be formatted as HTML5 XHTML files. For more information, see the
official epub3 specs.
BTW, you can easily test this for yourself. Create a new epub3 book, insert named entities such as and have it checked by epubcheck.
For example, the following code will fail epubcheck:
Code:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:epub="http://www.idpf.org/2007/ops">
<head>
<title></title>
</head>
<body>
<p> </p>
</body>
</html>
it'll only pass epubcheck if an entity definition is added:
Code:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html [
<!ENTITY nbsp " ">
]>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:epub="http://www.idpf.org/2007/ops">
<head>
<title></title>
</head>
<body>
