That's my understanding too.

From my limited understanding, UTF-8 does not embed NULs like Unicode does.
As such I would expect UTFs to just seem like ASCII strings with odd-ball
characters in it.

YAFFS does use strlen etc in a few places and it seems that strlen will just
count the non-NUL bytes which will be fine. If strlen tries to be clever and
count the number of UTF-8s then that will break.
