http://code.google.com/p/pidgin-win32-non-bmp/ is the plugin -
eoinrobb wrote it.

Yes, I've been meaning to do something like this.  I have an
incomplete patch that sanitizes problematic characters out of strings
(similar to what the plugin does).
I was hoping for a more central location to do this rather than for

The bug still hasn't been fixed in Pango - mostly because there isn't
a win32 maintainer currently.
This is the relevant bug: https://bugzilla.gnome.org/show_bug.cgi?id=668154
