It seems (I'm not through reading the manpage yet but I start to have a good idea of what is going on) that this will solve my problem. Thanks a lot.

# Solution for matching "é"
use locale ; 
my $test = "é é é é " ;
$test =~ /[[:alpha:]]/ and print "YEAH"  ; 
#OR 
$test =~ /[\w]/ and print "Thanx" ;

Simple for some, hard for me since I didn't even knew of localization.

Thank you Fletch! ( and diotalevi and jdporter who answered in the CB. )
