Is there a problem to submit the result file with strings in lower case?

The case of a name is ignored during evaluation, using the following UTF-8 aware lower-case conversion in Perl:

$enc = "utf-8";
.
.
.
$inputline = decode($enc, $inputline);
$inputline = encode($enc, lc($inputline));

To answer the question: It is perfectly fine to submit the result file with strings in lower case!
