There is no need to add two new items. Just replace in the current
implementation CF_TEXT with CF_UNICODETEXT, get/put wchar_t text, and convert
it from/to utf8.

This works fine because there is some magic in Windows which does char/wchar_t
conversion on the clipboard. So if someone puts an ASCII text with CF_TEXT on
the clipboard you will always be able to get the text with CF_UNICODETEXT.

A unicode aware application will not use CF_TEXT any longer.
