Under utf-8 encoding \xff is an illegal character.
I'm not sure if the two engines handle illegal characters in the same
way. Probably not, because one works byte-by-byte and the other a
character at a time.
These works fine:
:echo split("foo\x7fbar", "\x7f")
['foo', 'bar']
:echo split("foo\u00ffbar", "\u00ff")
['foo', 'bar']
