Answer 1

This is really a PHP question not so much a WP question -- but:

echo substr($stringx,0,strrpos($stringx,'-'));

Also I think your example #3 is wrong unless there are some cases where you want to exclude more than simply after the final dash character.

Note - if you want to exclude both that final blank space along with the final dash that immediately follows it, then change the substr length by -1 to avoid the final blank space:

echo substr($stringx,0,strrpos($stringx,'-')-1);

I fount where were problem...

https://codex.wordpress.org/Function_Reference/wptexturize

Each dash (short dash) is changing for long dash

I just wptexturize for titles by add to functions.php this code:

remove_filter('the_title', 'wptexturize');

and works well. But how can I get with long dash? I do not know... but I hope it will help someone in future.
