Good to know. For the time being this paragraph from the LuaTeX manual

is a bit misleading, since just unicode.utf8.find is again not
Unicode-aware. The same applies for the empty capture () in match and
gmatch, BTW. The output of
str = "abcde"
str = "Äabcde"
is 5 and 7. The second one is obviously wrong.
