# 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 &apos;
print "not " unless decode_entities("&apos;") eq "'" &&
                    encode_entities("'", "'") eq "&#39;";
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].
