Australian English does not place a period after titles that would end with the same letter as it would be unabbreviated.
e.g.
Mister = "Mr." in U.S. English and "Mr" in Australian English.
Reverend = "Rev." in both U.S. and Australian English.

it's true! american streams would always get my old tag wrong for this reason in my skullgirls playing days, and i also had to change my game publishing name from "CT Matthews" to "C.T. Matthews" because it turns out that omitting the periods in initials is much less common in the U.S. than in the UK too
I didn't even get to considering actual initials! That's kinda funny as well, though tough on having to slightly rebrand 😆.
