I did a little bit of digging and we will sometimes request `CF_TEXT` and `CF_OEMTEXT` (see `create_mime_stuff()` in this file). Technically we could change the pairings there and always request text data in `CF_UNICODETEXT`, but I would do some more testing and check if that doesn't cause regressions in some surprise spot.
