-// We could use CharNext() to generate grapheme cluster boundaries, but it doesn't handle surrogate pairs properly (see http://archives.miloush.net/michkap/archive/2008/12/16/9223301.html).
-// So let's use Uniscribe (see http://archives.miloush.net/michkap/archive/2005/01/14/352802.html)
-// See also http://www.catch22.net/tuts/uniscribe-mysteries and http://www.catch22.net/tuts/keyboard-navigation for more details.
