@babel/plugin-transform-unicode-regex transforms Unicode regexes to ES5-compatible expressions. This plugin ensures that regular expressions using Unicode features, like Unicode property escapes (\p{}) and named groups, function correctly in environments that don't natively support them. It analyzes regex patterns and rewrites them to use surrogate pairs and other ES5-compatible methods, maintaining functionality across older JavaScript engines. This is crucial for projects targeting legacy browsers or environments.
