🔧 This rule is automatically fixable by the --fix CLI option.

enforce the use of the u flag

📖 Rule Details

This rule reports regular expressions without the u flag.

It will automatically add the u flag to regular expressions 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 rule. The position of the report is improved over the core rule and arguments of new RegExp() are also checked.
