Can’t get first character

Some value can’t get.

object(A_Z_Listing)#2276 (12) { [“taxonomy”:”A_Z_Listing”:private]=> NULL [“type”:”A_Z_Listing”:private]=> string(5) “posts” [“alphabet”:”A_Z_Listing”:private]=> NULL [“unknown_letters”:”A_Z_Listing”:private]=> string(1) “#” [“alphabet_chars”:”A_Z_Listing”:private]=> NULL [“items”:”A_Z_Listing”:private]=> NULL [“matched_item_indices”:”A_Z_Listing”:private]=> NULL [“current_item”:”A_Z_Listing”:private]=> NULL [“current_item_index”:”A_Z_Listing”:private]=> int(0) [“current_letter_items”:”A_Z_Listing”:private]=> array(0) { } [“current_letter_index”:”A_Z_Listing”:private]=> int(0) [“query”:”A_Z_Listing”:private]=> NULL }

Thank you for helping me.

I think the problem comes from my database setup.
I added hard code for alphabet. = ))
See it:
$letters = array( “A” =>”A”,”Á” =>”A”,”À” =>”A”,”Ä” =>”A”,”” =>”A”,”a” =>”A”,”á” =>”A”,”à” =>”A”,”ä” =>”A”,”â” =>”A”,”B” =>”B”,”b” =>”B”,”C” =>”C”,”c” =>”C”,”D” =>”D”,”d” =>”D”,”E” =>”E”,”É” =>”E”,”È” =>”E”,”Ë” =>”E”,”Ê” =>”E”,”e” =>”E”,”é” =>”E”,”è” =>”E”,”ë” =>”E”,”ê” =>”E”,”F” =>”F”,”f” =>”F”,”G” =>”G”,”g” =>”G”,”H” =>”H”,”h” =>”H”,”I” =>”I”,”Í” =>”I”,”Ì” =>”I”,”Ï” =>”I”,”Δ =>”I”,”i” =>”I”,”í” =>”I”,”ì” =>”I”,”ï” =>”I”,”î” =>”I”,”J” =>”J”,”j” =>”J”,”K” =>”K”,”k” =>”K”,”L” =>”L”,”l” =>”L”,”M” =>”M”,”m” =>”M”,”N” =>”N”,”n” =>”N”,”O” =>”O”,”Ó” =>”O”,”Ò” =>”O”,”Ö” =>”O”,”Ô” =>”O”,”o” =>”O”,”ó” =>”O”,”ò” =>”O”,”ö” =>”O”,”ô” =>”O”,”P” =>”P”,”p” =>”P”,”Q” =>”Q”,”q” =>”Q”,”R” =>”R”,”r” =>”R”,”S” =>”S”,”s” =>”S”,”ß” =>”S”,”T” =>”T”,”t” =>”T”,”U” =>”U”,”Ú” =>”U”,”Ù” =>”U”,”Ü” =>”U”,”Û” =>”U”,”u” =>”U”,”ú” =>”U”,”ù” =>”U”,”ü” =>”U”,”û” =>”U”,”V” =>”V”,”v” =>”V”,”W” =>”W”,”w” =>”W”,”X” =>”X”,”x” =>”X”,”Y” =>”Y”,”y” =>”Y”,”Z” =>”Z”,”z” =>”Z”);
$this->alphabet = $letters;
$this->unknown_letters = $others;

Thank you again.
