Not all Unicode codepoints are supported by unicodedata.name(), but
they are supported in \N escapes and unicodedata.lookup. Is there a
reason for this?
Normally, you can do this:
>>> "\N{GREEK SMALL LETTER OMEGA}"
'ω'
>>> unicodedata.name(_)
'GREEK SMALL LETTER OMEGA'
But check this out:
>>> unicodedata.lookup("CHARACTER TABULATION")
'\t'
>>> "\N{CHARACTER TABULATION}"
'\t'
>>> unicodedata.name(_)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: no such name
>>> unicodedata.lookup("NULL")
'\x00'
>>> "\N{NULL}"
'\x00'
>>> unicodedata.name(_)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: no such name
Tested on 3.4, 3.5, and 3.6. Extremely odd.
