--fixoption on the command line (opens new window) can automatically fix some of the problems reported by this rule.
# 📖 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.

"unicodeCodePointEscape" // or "unicodeEscape"
