Ouch. Details?

Yep, given a font that actually supports them, e.g. SimSunExtB,
non-BMP chars should display correctly in mintty 0.5.

'fraid not. Mintty uses the Win32 GUI function ExtTextOut to paint
characters in its window, and that function does support surrogates.
The Cygwin DLL uses WriteConsole, which apparently doesn't support
them, and only MS can change that.
