# Hi. I've got a problem that has surfaced with the changes to
# HTML::Entities.pm for 5.11 (it doesn't happen with 5.08). It's happening
# in the process of encoding then decoding special entities. Eg, what goes
# in as "abc&def&ghi" comes out as "abc&def;&ghi;".
print "not " unless decode_entities("abc&def&ghi&abc;&def;") eq
"abc&def&ghi&abc;&def;";
print "ok 10\n";
# Decoding of '
print "not " unless decode_entities("'") eq "'" &&
encode_entities("'", "'") eq "'";
print "ok 11\n";

14. Proposed Entities
The HTML DTD references the "Added Latin 1" entity set, which only
supplies named entities for a subset of the non-ASCII characters in
[ISO-8859-1], namely the accented characters. The following entities
should be supported so that all ISO 8859-1 characters may only be
referenced symbolically. The names for these entities are taken from
the appendixes of [SGML].
