Re: \U, \E and friends interpolation in regex operators

[l.frankline]

Hi,

when you store Escaping characters like \U, \E, \u and so on... in a scalar variable, avoid using single quote instead of double quote, because the regex can't recognise the Escaping characters. If you do like $var = '\utext' the regex will interpolate. here is an example. try this:

print my $var = "\utext";
"Text" =~ m/$var/ && print "matches\n";
