I think the point is to explicitly request `CF_UNICODETEXT` and, if Clipboard has `CF_TEXT` or `CF_OEMTEXT` inside, it will automatically convert it to Unicode on output. This way we ensure we always get 2-byte Unicode text independently of Clipboard contents. So I would say to change the flavors in `create_mime_stuff()` as well.
