[New-bugs-announce] [issue26648] csv.reader Error message indicates to use deprecated

[Philip Martin]

New submission from Philip Martin:

Currently, the error message:

_csv.Error: new-line character seen in unquoted field - do you need to open the file in universal-newline mode?

is cryptic in that universal line mode has been deprecated, and will not run in Python 3.5., i.e.:
open(escape_path, "rU", encoding=ENCODING)
>>> DeprecationWarning: 'U' mode is deprecated

I think a message indicating a suggestion to open the file with newline='' to enable universal line mode is more insightful.
