i have written a parser which searchs in a file for regexps. it all went fine but then i found out, that some of the data files are encoded in unicode. i tried several things from manuals and books but it just doesn't work. it seems that perl does not use the right encoding, it finds almost no regularexpression and the output is still with the NULs after every character. if i write the same lines in ASCII-File the keywords are found without any problem. i am using windows xp with active state perl 5.8. thanks vor your help. 
#test.pl - testfile with the heart of the parser
#open the file to search trough
unless (open FILE, "<../perl/testproto/Protokoll.log") {
    die "Cannot open Keywordfile: $!\n";
}

#search for the regexp in the file
while (<FILE>) {
  chomp;
  if (/.*Cl(.*)/) {
    print $1;
     }
  else {
    print "Keine Treffer.\n";
  }
}
