In FFXI it wasn't necessary to have one in your inventory, merely necessary that you "Select" the item by placing the cursor over it for any duration. In fact having it in your inventory didn't achieve anything, you had to run the cursor over it, be it in your inventory, on the AH or in a /check of someone. That being said, I'm assuming those who are having trouble ran their cursor over it. I have no definitive answer for FFXIV unfortunately.
I will say that FFXIVyg you can swap between languages, worst case scenario copy and paste the Japanese item name, include both languages of the item name in your shout.
