Spellchecker in solr + marc 3.5.0

[HL]

Hi all,

I am using solrmarc + Vufind to index marc records.
solr version is 3.5.0

I am having issues trying to make solrmarc to suggest possible 
alternative spellings when querying the database BUT using a non Latin 
Based alphabet.

Quering *ounix* suggests *unix* alright

however when querying in say Greek alphabet words no suggestions are 
returned.

Thanks in advance for your suggestions

Regards,
Harry.
