zh = 'U+5EB8'
print(zh)	# U+5EB8

zh = '\u5EB8'
print(zh)	# 庸

zh = '\\u5EB8'
print(zh)	# \\u5EB8
print(zh.decode('unicode-escape'))	# AttributeError: 'str' object has no attribute 'decode'
print(zh.encode('ascii').decode('unicode-escape'))	# 庸

zh = b'\\u5EB8'
print(zh.decode('unicode-escape'))	# 庸

zh = '庸'
print(zh)	# 庸
print(zh.encode('utf-8'))	# b'\xe5\xba\xb8'
