I’ve added international encoding and locale support to the Amazon App of the Day feed. Here is the link for Spain, available right now:
Spain (Spanish): http://www.geekexile.com/amazon_rss-es.xml
Please note: This reflects the locale for Spain. This is NOT simply a translation! Amazon also occasionally offers different apps each day for each locale.
If you have a particular locale you would like added, please let me know.
