{{ 42 > ' foo' ? '.' : 'F' }}
{{ 42 == "42\f" ? '.' : 'F' }}
{{ 42 > "\x00\x34\x32" ? '.' : 'F' }}(https://twigfiddle.com/h5x8fk)
PHP:
echo 1 === twig_compare(42, ' foo') ? '.' : 'F', "\n";
echo 0 === twig_compare(42, "42\f") ? '.' : 'F', "\n";
echo 1 === twig_compare(42, "\x00\x34\x32") ? '.' : 'F', "\n";

I guess the fixes would be like
(1) use a new variable for the trimmed string and use it except in return (string) $a <=> $b;, and
(2) trim explicitly the chars " \t\n\r\v\f" (from https://github.com/php/php-src/blob/php-7.4.7/Zend/zend_operators.c#L3041), because the default misses \f and includes \0.
