[New-bugs-announce] [issue39174] unicodedata.normalize failing with NFD and NFKD for some characters in Python3

[Lee Collins]

New submission from Lee Collins <lcollins at netflix.com>:

A script that works in 2.7.17 is now failing for some Unicode characters in 3.7.5 on MacOS 10.14.6. For example unicodedata.normalize('NFD', 'à') used to return the correct decomposition u'a\u0300', but in 3.7 it returns the single composed character U+00E0. This doesn't happen for all composed forms, just some. Other examples: á, ã
