Thanks mortiz. Yes I noticed that Net::Amazon is sending requests against the 2009 version of the Amazon API but I'm wondering how much of a problem that might be? Yes, it's working but am I missing out on some must-have features or will I get slower responses as a result? I was just wondering what others use because I'm just starting with this and, to my surprise, I couldn't find anything more recent at all. I might be missing something obvious and I'm imagining that many others are using this API on a daily basis. Is it considered better to just parse the XML response 'manually' instead of relying on a wrapper module that might not be maintained anymore?
Thanks for your hints about the Unicode issues.
