bpo-30688: Import unicodedata only when needed. (GH-5606)
...
Importing unicodedata in sre_parse leads to failure in compilation.
unicodedata is unused during compilation, and is not compiled when this
file is imported. The error occurs when generating posix variables,
pprint is required. The dependency chain goes on like this:
sysconfig -> pprint -> re -> sre_compile -> sre_parse (this file)
