If the API is improved, I suggest that the API of the proceduers which
convert into and from UTF is improved as well.
I designed the original API, to allow conversions to stop when memory for
the target string runs out (in those conversions, it is not known in
advance how long will the target string be) and resume from that point on.

However, the API involves calling procedures with long argument lists, and
I am not happy with this approach.

I suggest to modify the API to use object-oriented approach (of course,
using C):
1. Define a struct, which describes a conversion - with pointers to source
   and destination strings, and length fields.
2. Implement a function, which initializes the struct.
3. Change the long argument lists in the conversion procedures to a
   pointer to the struct.
4. Each time a conversion procedure is called, it modifies the object to
   describe the state of the conversion in progress.
