      Hi Glenn,

      I've looked at your patch, it looks exactly like what I'm looking for.

      I'm going to try compiling with it today and I'll let you know my results.

      I implemented it a while back. I just updated my source tree; attached
      is the patch. It's mostly unchanged from back then, I think.

      There are two Windows clipboards; ANSI and Unicode. The ANSI one must
      be ANSI codepage text, and the Unicode one in UCS-2.

      The attached patch attempts to put text in the Unicode clipboard, and if
      that fails (eg. we have no conversion path to Unicode), puts it in the
      ANSI clipboard. There's no need to duplicate the data in both, since
      Windows will convert it in the background (eg. if an app asks for CF_TEXT
      and only CF_UNICODETEXT is available, it'll be converted.)

      According to MS documentation, CF_UNICODETEXT is available all the way
      down to Win95:
