http://wiki.c2.com/?RawStrings
Raw string 是个通用概念。即 escape 不生效的 string，既然不生效，也无法 escape 掉 ending sequence。
所有语言的 raw string 都面临一个问题，即如何处理 ending sequence 

Python
https://docs.python.org/3/reference/lexical_analysis.html#string-and-bytes-literals
staring sequence: “ or '
ending sequence: “ or '
Python 的做法是允许 ‘, “ 出现，但需要用 \ escape 掉它们（相当于在 Python raw string里有唯一生效的escape就是\”和\’），并且 \ 依然会出现
