Details:

Hi, 

with perl 5.10 the semantic of unpacks U0 parameter changed from a charbased
to a bytebased version [1]. That means that _utf8_to_sgml from CharEnt.pm
fails for multibyte characters. The fix is pretty simple:

-$char = unpack('U0U*',$1);
+$char = unpack('C0U*',$1);

Of course this took me some time to findout ;). You should around it with
a perl version check, but I guess that should be no Problem. 

Thanks
