SQLite - Queries with non-english characters show no results

I am using the SearchView widget and it works well except for the fact that if the line I was entering contains any non-english character the result is empty even though it is clear that there are ARE results

Example:

In the above image, there are two results for the string "chu" , but if I type "-" the ListView does not show any results, and it will be obvious that there are results.

This is what I have tried so far

public Cursor searchProductByDescription(String description) {
        String where = PRODUCT_DESCRIPTION + " LIKE LOWER( ? ) ";
        String[] whereArgs = { "%" + description + "%" };   

        this.openReadableDB();
        Cursor cursor = db.query(PRODUCT_TABLE, null, where, whereArgs, null,
                null, null);

        if (cursor != null) {
            cursor.moveToFirst();
        }
        this.closeDB();
        return cursor;
}

      

        
        
        
      

    

I'm not sure if this is a searchview or SQLite widget related issue. I've seen a couple of questions where they suggest converting a string to a LOWER o UPPER case, but this solution didn't work for me.

I would really appreciate if you could help me here. Thanks to
