So, '&x128;' is an entity ? Is't really true ?

Well, unless you want to put in some knowledge about which identifiers
are known entities, I don't see how to reject that.  It's not a numeric
entity, sure, but it looks just like a named entity.

I see. I think in future we'll improve parser<->dictionaries interaction,
so it could be possible to have dict_html dictionary, which encapsulate
all html-specific knowledge.

'ካ' and  '&128;' are numeric character reference entities.

'&x128;' is (syntactically) a named entity (because there is no #
following the &).

This fix applies to numeric character reference entities, not to named
entities.

I mean '€' of course.
