British placement of punctuation relative to inverted commas

Question

I already found many related questions, but no sourced and exactly fitting answers, so I have to ask again.

I know there are different standards. I am interested in the British one. I was under the impression that punctuation was to be enclosed within the inverted commas, if and only if it formed part of the utterance. To my understanding, the following sources corroborate my statement (please note the position of the bold face comma):

Example from it:

‘Economic systems’, according to Professor White, ‘are an inevitable byproduct of civilization, and are, as John Doe said, “with us whether we want them or not”’.

Edit: This one seems to be wrong. Unfortunately, I followed it for months.

Example from it:

"Hello", he said. "How are you today?"

Shockingly, it appears that the following contradicts my interpretation: living oxford dictionaries

namely in the examples:

‘You’re right,’ he said.

and

‘I don’t agree,’ I replied.

Am I overlooking something? Is the standard changing? I am very confused!

Answer 1

You're confusing the usage of quotation marks for direct speech and for "a word or phrase that’s being discussed, or that’s being directly quoted from somewhere else". (Oxford Dictionaries)

In direct speech, both British and American English put the punctuation mark inside the quotation.

"I would like to know how this occurred," he said.

The versions of English differ in direct quotes, with regards to commas and periods. British English puts them outside the quotation marks whereas American English puts them inside.

British

I am what you would call a "renaissance man".

American

I am what you would call a "renaissance man."

As Peter Shor helpfully pointed out, the punctuation goes inside the quotation marks if it is part of the direct quote, regardless of whether it is British or American.

Before his execution, Ned Kelly famously said "Such is life."
