lua_pushstring is auxiliar (as you pointed out); the same for
lua_dostring (the "official" luaL_loadbuffer gets a size). luaS_new
and luaO_chunkid may need some rework.

an external Unicode system. Suggestions?

We try to make it string width independent, but it is difficult to
ensure that. We will try to improve that (maybe after 5.0 beta).
