Thanks!

Couldn't this be done without introducing Windows-specific options?
AFAIK, the logic employed by Windows when it encodes clipboard text is
quite simple, something like: if it cannot be encoded with the system
codepage, use Unicode. Why cannot Emacs simply follow this logic?
Also, AFAIK CF_UNICODETEXT _can_ be used on Windows 9x, as any
program like clipbrd.exe or ClipConvert will show you.

Is that optimization indeed an optimization? That is, does it give us
any significant speed-up? Can you measure the speed of pasting a
large chunk of ASCII text in an Emacs that has this optimization and
compare it to the speed of pasting non-ASCII text?
