I have a string,

'This may be our situation. It is similarly fantastical to expect people who cannot afford food\xc2\xa0\xe2\x80\x94 as will soon be the case for many more\xc2\xa0\xe2\x80\x94 to practice personal hygiene. You can\xe2\x80\x99t eat soap. If you are starving, you won\xe2\x80\x99t buy it.'

I have to remove the unnecessary string like, '\xc2\xa0\xe2\x80\x94' from the string. The patter which I can observe is this unnecessary string starts with '\' and ends with a number.

Thanks so much for the help.
