I see one potential problem: in kqueue-add-watch, you encode the file
name, but then pass it to APIs that generally expect multibyte
(i.e. un-encoded) strings, although they will also work with encoded
unibyte strings. Moreover, you put the unibyte encoded file name into
the watch object. Not sure if this is related to the issue at hand,
but it would be cleaner to make this change:
diff --git a/src/kqueue.c b/src/kqueue.c

Btw, I don't think I understand the nature of the problem yet: where
were the unibyte strings shown in the report printed? Did some Emacs
code print them, and if so, where is that code?
