至少在Python 2中,unicodedata.name()不识别某些字符.

>>> from unicodedata import name
>>> print(u'\n')
>>> name(u'\n')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: no such name
>>> name(u'a')
'LATIN SMALL LETTER A'

(第一个print是证明Python本身可以识别u'\n'为换行符.)
当然Unicode 包含字符\n,它有一个名称,特别是"LINE FEED".
NB.unicodedata.lookup('LINE FEED') …
