in reply to What happenend to the Umlaut ? [SOlVED]

Not sure what you're asking... It seems to me you're using Encode::encode_utf8 and Data::Dump::dd? If so, two things happened:
  1. "Karl Dämlich" was encoded in utf-8: 
    $customer = encode_utf8($customer);

  2. The encoded form of "Karl Dämlich" was displayed by Data::Dump::dd as "Karl D\xC3\xA4mlich". The cursory scan of the Data::Dump's source suggests that it was done by the quote function: 
    sub quote {
  ...
  s/([\0-\037\177-\377])/sprintf('\\x%02X',ord($1))/eg;
  ...
}

    presumably to make its representation unambiguous.
