The uu module can be run as command-line tool. In Python 2, "uu -t infile outfile" opens input file in text mode, i.e. convert '\r\n' to '\n' on Windows and '\r' to '\n' on Mac Classic, and "uu -d -t infile outfile" opens output file in text mode, i.e. convert '\n' to '\r\n' on Windows and '\n' to '\r' on Mac Classic. In Python 3 this option has no effect.

The proposed patch restores former behavior and extends it. Encoding with -t option now uses universal newlines for reading, and decoding with -t option now converts '\n' to os.linesep for writing. In additional text mode now works with standard input/output.

This change perhaps is too large for the fix of such insignificant bug and that is why I propose it as a new feature.

Could it be argued that this is a regression so the type should be behavior and not enhancement?

Note the uu module is deprecated in 3.11 and set for removal in 3.13.

See PEP 594 – Removing dead batteries from the standard library and #91217.
