I don't see which usecase is not covered by TextIOWrapper. But I know some cases which are not supported by StreamReader/StreamWriter. This could be be partially fixed by implementing generic StreamReader/StreamWriter classes that reuse the incremental codecs, but I don't think thats worth it. Why not? We have already an implementation of this idea, it is called io.TextIOWrapper.

Exactly.

From another post by Victor:

As I wrote, codecs.open() is useful in Python 2. But I don't know any program or library using directly StreamReader or StreamWriter.

So: implementing this is a lot of work, duplicates existing functionality and is mostly unused.

Servus, Walter
