+ *
+ * We return a 0 on success or a -1 on error. An error also sets errno to
+ * E2BIG, EILSEQ, or EINVAL (see below); otherwise errno will be set to 0.
+ * The "in" xbuf is altered to update ".pos" and ".len". The "out" xbuf has

+ *
+ * If ICB_CIRCULAR_OUT is set in "flags", the chars going into the "out" xbuf

+ * multi-byte character at the physical end of the ".buf" (though no reducing
+ * happens if ".pos" is <= 1, since there is no room to wrap around).
+ *
+ * If ICB_EXPAND_OUT is set in "flags", the "out" xbuf will be allocated if
+ * empty, and (as long as ICB_CIRCULAR_OUT is not set) expanded if too small.
+ * This prevents the return of E2BIG (except for a circular xbuf).
+ *
+ * If ICB_INCLUDE_BAD is set in "flags", any badly-encoded chars are included
+ * verbatim in the "out" xbuf, so EILSEQ will not be returned.
+ *
+ * If ICB_INCLUDE_INCOMPLETE is set in "flags", any incomplete multi-byte
