A thing about guild tag characters

Hey guys,
so I decided to make myself a guild and opened the Path of Exile wiki and found my correct characters but then I had a small problem when trying to find lowercase g. On the wiki it says it's supposed to be
Peninsula map but when I slot it in the tag editor it's the character 8.
I need some help. I don't want to buy all of the maps available and test them myself.
Thanks in advance! :)
