Code Inspection: Escaped meta character
Reports the escaped meta characters. Some RegExp coding styles specify that meta characters should be placed inside a character class, to make the regular expression easier to understand. This inspection does not warn about the meta character [, ] and ^, because those would need additional escaping inside a character class.
Example:
\d+\.\d+
After the quick-fix is applied:
\d+[.]\d+
