Can't escape the backslash with regex?

Question

I\'m using the following regex

^[a-zA-Z0-9\\\',!;\\?\\$\\^:\\\\\\/`\\|~&\\\" @#%\\*\\{}\\(\\)_\\+\\.\\s=-]{1,1000}$

I know it\'s ugly,

Answer 1

The backslash \ is the escape character for regular expressions. Therefore a double backslash would indeed mean a single, literal backslash.

\ (backslash) followed by any of [\^$.|?*+(){} escapes the special character to suppress its special meaning.
