Python is aware of unicode codepoint aliases, but unicodedata does not provide a way to find aliases of a given codepoint:

>>> ucd.lookup('ESCAPE') == '\N{ESCAPE}'
True
>>> ucd.lookup('RS') == '\N{RS}'
True

but

>>> ucd.name('\N{ESCAPE}')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: no such name


>>> ucd.name('\N{RS}')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: no such name
