In this case you could use `query-replace-regexp` replacing \ with n The "\<\>" brackets match beginning and end of words: https://www.gnu.org/software/emacs/manual/html_node/emacs/Regexp- Backslash.html Your character also seems to appear inside maths expressions only. In this case you could use the function defined in this post: http://stackoverflow.com/questions/19845598/emacs-regex-replacing-a-string-inside-a-latex-equation it's very useful and I use it regularly in LaTeX documents.
