Special characters are converted by the browser into their hexadecimal ascii values (with a % in front of them). You can either use CGI.pm to parse the query string for you, or do something like this:

#split the query string by key/value pairs
my @unparsed = split(/&/, $query);
 for $pair(@unparsed) {
# split the key and value for each pair
 my ($key, $value) = split(/=/, $pair);
#substitue pluses for spaces
 if ($value =~ /\+/) { $value =~ s/\+/ /g; }
#look for hex values (this could be a better regex)
  while ($value =~ /\%((\d¦\w)(\d¦\w))/g) {
  my $val = $1;
  my $hex_val = hex($val);
#replace all occurrences of the hex value with the character
  $value =~ s/%$val/chr($hex_val)/eg;
  }
#store results in a hash
 $params{$key} = $value;
 }
