There are several examples in the sources of calling Lisp from C. As
just a random example:
if (STRINGP (curdir))
val = call1 (intern ("file-remote-p"), curdir);
This calls the Lisp function file-remote-p with one argument, curdir.
If you tell me more about the arguments and the expected effects of
calling uni_compose and uni_decompose, maybe I could propose a
specific implementation. The Harfbuzz documentation doesn't seem to
tell enough, or maybe I didn't find the right text.
Thanks.
