It could be I that is missing something, but AIUI the module API already
provides module_make_string for creating a multibyte Lisp string from a
C string, which can then be passed to one of the aforementioned
functions via module_funcall, no?

In other words, I'm asking whether the aforementioned functions are in
any way a better alternative to the encode-coding-string approach
previously proposed.

Thanks,
