Hi Eyal, ICUFoldingFilter uses http://site.icu-project.org under the hood. If you think there is a bug, it is better to ask its mailing list.

It seems that ICUFoldingFilter converts FA04 to 5B85, which results in the wrong character being indexed. Does anyone have any idea if and how this can be resolved? Is there an option to add an exception rule to ICUFoldingFilter? Thanks, Eyal
