No, but it's not too hard too change the existing patch.

Basically you'd need to apply Fedora's patch, and then (sorry no proper 
patch here but it's not a big deal)

in slint.c, use

  SLtt_get_terminfo()
+#if SLANG_VERSION >= 20000
+ SLutf8_enable (-1);
+#endif

in help.c, use

#if defined(UTF8) && SLANG_VERSION < 20000
                       SLsmg_draw_object (h->y + line + 2, h->x + col + 2, acs_map [c]);
#else
                       SLsmg_draw_object (h->y + line + 2, h->x + col + 2, c);
#endif /* UTF8 */

and then (possibly global.h isn't the best place though):
