You can use any kind of (L)etter, but not (S)ymbols:

    >>> list(map(unicodedata.category, "蟒蠎"))
    ['Lo', 'Lo']

    >>> 蟒, 蠎 = "Chinese Python", "Japanese Python"

    >>> list(map(unicodedata.category, "∂∫"))
    ['Sm', 'Sm']

    >>> ∂ = "Partial Differential"
      File "<stdin>", line 1
        ∂ = "Partial Differential"
          ^
    SyntaxError: invalid character in identifier

    >>> ∫ = "Integral"
      File "<stdin>", line 1
        ∫ = "Integral"
          ^
    SyntaxError: invalid character in identifier
