That appears to be the only Symbol Math character which is accepted as
an identifier in Python 3.5:
py> import unicodedata
py> all_unicode = map(chr, range(0x110000))
py> symbols = [c for c in all_unicode if unicodedata.category(c) == 'Sm']
py> len(symbols)
948
py> ns = {}
py> for c in symbols:
... try:
... exec(c + " = 1", ns)
... except SyntaxError:
... pass
... else:
... print(c, unicodedata.name(c))
...
℘ SCRIPT CAPITAL P
