Code Inspection: Escaped meta character

Reports 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+
