This is not true. I tested UTF-8 support with sc(4) in FreeBSD 8 and it worked fine.
It required some kernel options:

options SC_PIXEL_MODE
options VESA
options         TEKEN_XTERM
options         TEKEN_UTF8

And optionally for /boot/device.hints:

hint.sc.0.flags="0x180"		# switch to graphics mode at boot time
hint.sc.0.vesa_mode="0x1F0"	# preferred framebuffer video mode code

And the port sysutils/jfbterm to render fonts.
