public class RemoveAllAccentsFilter
extends org.apache.lucene.analysis.TokenFilter

Removes any accents from the input. NOTE: Lucene includes ASCIIFoldingFilter, but this works with non-ASCII characters too. Uses Normalizer, so Java 1.6+ is needed. If this is not available, use an approach such as RemoveDutchAccentsFilter.
