Laravel requires the mbstring extension to be installed.

I got in this time this error, laravel not notice abount this extension, I believe that termwind can be have.

Laravel does require the mbstring extension, but that requirement can be solved with symfony/polyfill-mbstring. But not completely, because that polyfill doesn't contain every function. The readme file says it's a partial implementation. And mb_strimwidth (https://github.com/symfony/polyfill-mbstring/blob/e5e7ddb00b859dbdf5ad8f3bbe4cd29a3a37aa34/Mbstring.php#L62) is one of the not implemented functions.
