I haven't looked closely, but I vaguely remember that I had thought in the past,
(a version of) type2char() should be made part of R's API. Exactly because of the reason you give.

A more sensible name for the exported function would probably be R_type2char or
Rtype_to_char or
Rtype_as_char

If you are going to provide a patch (against R-devel), you'd ideally also include the corresponding entry in doc/manual/R-exts.texi ... (:-)
