Subject: utf8 flag is randomly maintained in autoactions on v5.20+
Download (untitled) / with headers
text/plain 859b
package G; use Regexp::Grammars; my $parser = qr{ <TOP> <rule: TOP>.* }xms; sub interpret { my ($text, $actions) = @_; $parser->with_actions( $actions ); return $text ~~ $parser; } package A; use Encode; use Mouse; sub TOP { my ($self, $match) = @_; printf "TOP autoaction, match=%s is_utf8=%s\n", $match, Encode::is_utf8($match); return $match; } package main; use utf8; G::interpret( 'zażółć gęślą jaźń', A->new); # some polish text G::interpret( 'שלום העולם', A->new); # some RTL text __END__ On Perl 5.20.1 and 5.21.5 it gives following result: --- TOP autoaction, match=zażółć gęślą jaźń is_utf8= TOP autoaction, match=שלום העולם is_utf8=1 --- Flag utf8 is lost for first unicode string but preserved for second. Both are expected to have it.

Thanks for this report also. The behaviour is most likely related to that reported already under https://rt.cpan.org/Ticket/Display.html?id=99980 which has been passed on to teh core developers. Damian
