Answer 1

Not sure if this is appropriate for your situation, but you could try using unicode_escape:

>>> t
'\\u0048\\u0065\\u006c\\u006c\\u006f\\u0020\\u20ac\\u0020\\u00b0'
>>> type(t)

>>> enc_t = t.encode('utf_8')
>>> enc_t
b'\\u0048\\u0065\\u006c\\u006c\\u006f\\u0020\\u20ac\\u0020\\u00b0'
>>> type(enc_t)

>>> dec_t = enc_t.decode('unicode_escape')
>>> type(dec_t)

>>> dec_t
'Hello € °'

Or in abbreviated form:

>>> t.encode('utf_8').decode('unicode_escape')
'Hello € °'

You take your string and encode it using UTF-8, and then decode it using unicode_escape.
