To cater to potentially state-dependent encodings, we have to reset the conversion descriptor into its initial shift state to properly finish the conversion. Furthermore, state-dependent encodings may not show progress when comparing `in_left` before and after the conversion; we rather have to see whether `out_left` has decreased. Also we have to cater to the fact that the final potentially state resetting call does not signal failure, but we still have to break respective loops afterwards.

If there are no objections, I'll merge this in a week. |
