[PHP-NOTES] note 130283 added to function.rawurlencode

I had an issue with multibyte character encoding, my implementation below:
```php
function mb_rawurlencode(string $url): string
{
    return implode('', array_map(
        static fn (string $char): string => preg_match('/[\w-]/', $char)
            ? $char
            : sprintf('%%%s', wordwrap(strtoupper(bin2hex($char)), 2, '%', true)),
        mb_str_split($url)
    ));
}
```
