[issue46947] unicodedata.name gives ValueError for control characters

[Joe Cool]

New submission from Joe Cool <snoopyjc at gmail.com>:

unicodedata.name gives ValueError for control characters, for example:

>>> unicodedata.name('\x00')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: no such name
>>> unicodedata.name('\t')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: no such name


Where unicodedata.lookup clearly knows the names for these characters:
>>> unicodedata.lookup('NULL')
'\x00'
>>> unicodedata.lookup('TAB')
'\t'
