Serhiy Storchaka added the comment: Chris, you did a great job on improving the documentation (including about universal newlines). Can you help with this issue? For the first stage should be clearly shown that "U" mode is not only should not be used in new code, but must be removed from the o

Nadeem Vawda added the comment: +1 for the general idea of deprecating and eventually removing the "U" modes. But I agree with David, that it doesn't make sense to have separate steps for 3.5 and 3.6/4.0. If you make the code raise an exception when "U" is used, how is that different from what

[issue15204] Deprecate the 'U' open mode

New submission from Serhiy Storchaka : Since Python 2.3 many open functions supports "Universal line mode" (PEP 278). Since 3.0 (and 2.6) PEP 3116 suggests better alternative -- io.TextWrapper. Now support for the 'U' mode in the different open functions is heterogeneous. Some functions simply
