TFA mentions s/Philosopher/Sorcerer/ in HP, which I confess to having confused me greatly (are Americans THAT ignorant that they are unaware of the concept?) and pleased me, since the Canadian publishing house stuck with en-GB throughout, AFAICT.
As a multilingual Canadian capable of understanding most English and French accents, I'm grateful for those who preserve and persevere with their home patois.
Funnily enough, I had a hard time with Bradley's accent the first time viewing Hot Fuzz but many hours of BritBox and Acorn and a few hours of HarbourCustoms later, no problems at all!
