Although in Preferences both versions of English are shown, in the Language window of the Characters panel the only option is English, main no distinction between any of the many variations of English.
And as I mentioned before, when I run a spell check my usual English spellings of words such as colour are wrongly flagged up. An important issue for those of us who work in the UK, and probably on Canada, Australia, New Zealand, South Africa etc, who generally follow British spelling norms and not those favoured by the US.
This forum is this same, constantly changing my English spellings for the US equivalent.
