Diacritics autocomplete

Hello,

I’m using a Lookup field in Formidable Forms to select street names from another form. The source list contains Romanian street names with diacritics (e.g., Ariniș, Ștefan cel Mare, Timișoara).

The autocomplete works only if the user types the exact name with diacritics.
If they type without diacritics (e.g., Arinis, Stefan cel Mare, Timisoara), no results are shown.

Since most users will type without diacritics, I need the Lookup autocomplete to be diacritic-insensitive (similar to case-insensitive matching), so that typing either version will match and display the correct entry.

Could you please provide guidance or a code snippet that makes the Lookup autocomplete ignore diacritics while keeping the original values in the source list unchanged?

Thank you.
