Ticket <URL: https://rt.cpan.org/Ticket/Display.html?id=76042 >
attached is the patch to introduce unicode support to the Win32::Clipboard
module,
which I happen to implement for my needs and now intent to share.
I decided not to support $CLIPB->... interface for these 2 new functions,
because
I dislike the concept of fake OO.
Also, the patch increments the module version number.
Thanks in advance for considering this,
regards,
Vadim.
