The input column name in pandas.dataframe.query() contains special characters.
I saw the change in 0.25, but still have . \ / 等问题
And main problem is that I can't restore these characters after converting them to "_" , which is a very serious problem.

I have an idea

input： pandas.dataframe Intermediate processing： `x2E`(Hex)-> like pandas`x2E`dataframe(Add backslashes after processing the data) ->pandas\x2Edataframe output pandas\x2Edataframe
