Solr spellcheck polish characters

Question

I would be more than grateful for information if sb was able to configure spellcheck in SOLR, so queries returns values when polish characters were replaced with unicoded?

I have spellcheck enabled however I am not getting any results when searching 'slub', while I am getting plenty for 'ślub'

Cheers

You should add an ASCIIFoldingFilterFactory in you spellchecking field configuration.

<filter class="solr.ASCIIFoldingFilterFactory" preserveOriginal="false"/>

Converts alphabetic, numeric, and symbolic Unicode characters which are not in the first 127 ASCII characters (the "Basic Latin" Unicode block) into their ASCII equivalents, if one exists.
