Hello Angel,

From the query you have posted i observe the following.

The function is tripping because the ^(caret) is outside the brackets([]) They need to be inside.

Using the æ for testing is perfectly ok the regex performs perfectly, once the caret is placed within the brackets.

my $in = "æ";

if ($in !~ /\w/) {print "contains non alpha numeric characters!!"; } else {print 'its all OK (_)';}

This should clarify your doubts. Cheers!!!
