Slight issue with PHP 8.0: error on usage of curly braces

I’ve been updating many of my sites to PHP 8.0 to see what breaks, and it looks like Google Analyticator is unfortunately among the ‘fail’ crowd:

PHP Fatal error: Array and string offset access syntax with curly braces is no longer supported in <WP-PATH>/wp-content/plugins/google-analyticator/google-api-php-client/src/service/Google_Utils.php on line 58

This is actually very easy to fix, just change line 58 from

$ordinalValue = ord($str{$ret});

to

$ordinalValue = ord($str[$ret]);

That’s it!
