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

enforce consistent usage of unicode escape or unicode codepoint escape

📖 Rule Details ​

This rule aims to enforce the consistent use of unicode escapes or unicode code point escapes.

This rule does not check for characters that require surrogate pairs (e.g. \ud83d\ude00, \u{1f600}) and patterns that do not have the u flag.

If you want to enforce a character that requires a surrogate pair to unicode code point escape, use the regexp/prefer-unicode-codepoint-escapes rule.
