	My terminal emulator does not display emoji, nor does any
	terminal emulator or font that NetBSD ships out of the box as
	far as I know, so it comes out instead as a couple of empty
	squares of different sizes.

	I think we should turn this cutesy/annoying `feature' off by
	default.

>How-To-Repeat:

	run gdb

>Fix:

	Yes, please!
