The admittedly old perl pages (perl 5.6) I have handy right now include
the
following near the top of the perlunicode page. I strongly doubt this
has
changed in 5.8.
Byte and Character semantics
Beginning with version 5.6, Perl uses logically wide characters to
represent strings internally. This internal representation of
strings
uses the UTF-8 encoding.
I've also found text suggesting the same in Chapter 15 of the Camel
book.
Unfortunately, I don't have another explanation for the doubled memory
consumption.
