FWIW, excluding the stuff obviously not in UTF8 (logo.gif and 
tools/power/cpupower/po/{de,fr}.po) we have

lib/fonts/font_7x14.c
lib/fonts/font_8x16.c
lib/fonts/font_8x8.c
lib/fonts/font_pearl_8x8.c
arch/s390/kernel/ebcdic.c
	crap in comments
arch/m68k/hp300/hp300map.map
drivers/tty/vt/defkeymap.map
	non-UTF8 - literals for compose statements
arch/arm/crypto/sha256_glue.c
arch/arm/crypto/sha256_neon_glue.c
kernel/events/callchain.c
	Latin1 copyright symbol (0xa9)
drivers/staging/rtl8188eu/include/odm.h
	Latin1 inverted ! (0xa1)
Documentation/devicetree/bindings/net/nfc/pn544.txt
	Latin1 superscript 2 (0xb2), in I²C
arch/arm/boot/dts/sun4i-a10-inet97fv2.dts
	Latin1 o-umlaut (0xf6) in David Lanzendörfer
drivers/crypto/vmx/ghashp8-ppc.pl
	a bunch of Latin1 middle dots (0xb7), in comments inside string constant
used to produce asm output, no less
drivers/gpu/drm/amd/include/atombios.h
	several U+FFFD in there - buggered conversion to UTF8?
drivers/gpu/drm/r128/r128_drv.h
	ditto, but here it's possible to figure out what got buggered -
Michel D�zer <daenzerm@...dent.ethz.ch> that presumably should've been "Dänzer"
drivers/iio/dac/ltc2632.c
	Latin1 e-acute in Maxime Roussin-Bélanger
drivers/power/reset/ltc2952-poweroff.c
	ditto in René Moll
drivers/spi/spi-omap-100k.c
	a couple of U+FFFD in Juha Yrjölä <juha.yrjola@...ia.com> - o- and a-umlaut
In this case the actual spelling is trivially googled.
drivers/spi/spi-omap2-mcspi.c
	ditto
drivers/usb/misc/iowarrior.c
	U+FFFD in Stéphane Doyon <s.doyon@...eotron.ca> - e-acute
drivers/visorbus/visorbus_main.c
	U+FFFD in place of copyright symbol
