Came here to provide exactly that link (canonical: <https://perldoc.perl.org/perlre#Script-Runs https://perldoc.perl.org/perlre#Script-Runs>). For those who figured they'd skip over it, it's pretty neat IMO. Perl 5.28 (released 2018) added a new technique for matching patterns that aren't all from the same Unicode script, a "script run." >In most places a single word would never be written in multiple scripts, unless it is a spoofing attack. An infamous example, is >>paypal.com >Those letters could all be Latin (as in the example just above), or they could be all Cyrillic (except for the dot), or they could be a mixture of the two. In the case of an internet address the .com would be in Latin, And any Cyrillic ones would cause it to be a mixture, not a script run.
