CSV Parser: Check and Convert the Encoding

Many CSV-Files generated by Excel are encoded in ISO-8859-15.
Probably it is posible to check the Encoding and change it if necessary.

I propose to add the following line to the ParserCSV.inc - File at line 199:
$line = iconv('ISO-8859-15', 'UTF-8', $line);
or similar.
