In [18]: c = '你好'                                             
In [20]: d = c.encode('unicode_escape')                         
In [21]: d
Out[21]: b'\\u4f60\\u597d'
In [23]: e = d.decode('utf-8')                                  
In [24]: e
Out[24]: '\\u4f60\\u597d'
In [25]: type(e)
Out[25]: str
In [26]: f = e.encode('utf-8').decode('unicode_escape')        # 在字符串中要将Unicode字符转换未中文,需要先编码. 
In [27]: f
Out[27]: '你好'
