regexp/require-unicode-regexp

enforce the use of the u flag

• 🔧 The --fix option on the command line (opens new window) can automatically fix some of the problems reported by this rule.

📖 Rule Details

This rule reports regular expressions without the u flag.

It will automatically add the u flag to regular expression where it is statically guaranteed to be safe to do so. In all other cases, the developer has to check that adding the u flag doesn't cause the regex to behave incorrectly.

This rule is inspired by the require-unicode-regexp (opens new window) rule. The position of the report is improved over the core rule and arguments of new RegExp() are also checked.
