Check if DLD contains non-ascii characters

Browse source 
Valid divelogs.de export might contain non-ascii characters in CDATA
fields as long as these characters are found in iso-8859-1. So we'll
have to test to make sure the content is fully ascii before calling
xmlStringLenDecodeEntities to decode possible character references.
