New submission from Jirka Marsik <jiri.mar...@oracle.com>:
re.compile(r"\N{name of Unicode Named Character Sequence}"), e.g.
re.compile(r"\N{KEYCAP NUMBER SIGN}"), throws a TypeError. The regular
expression parser relies on 'unicodedata' to lookup character names. The
'unicodedata' module recently added support for Unicode Named Character
Sequences (https://www.unicode.org/Public/13.0.0/ucd/NamedSequences.txt).
Trying to use these named character sequences in a regular expression leads to
a 'TypeError', as the regexp parser tries to call 'ord' on a string with length
> 1.
