[New-bugs-announce] [issue15216] Support setting the encoding on a text stream after creation

[Nick Coghlan]

New submission from Nick Coghlan <ncoghlan at gmail.com>:

As discussed on python-ideas, swapping out the sys.std* streams can be fraught with peril. This can make writing code that wants to support an "--encoding" option for pipeline processing difficult.

The proposal [1] is that TextIOWrapper support a set_encoding() method that is only supported between creation of the stream and the first read or write operation. Once the stream is "dirty", you can no longer change the encoding - you must replace the stream (e.g. by passing stream.fileNo() to open())
