"Charlie Charlie" is often heard when flying through Africa or places utilising HF radio and where English is not the native tongue
The term originates from marine code flags, with "C" being "yes" "affirmative"or the significance of the previous code group should be read in the positive".
It is not standard RT but is used and seems to be understood.

Toolish,
You'll find that there are quite a few RT phrases the are specific to Australia and not ICAO standard, much like there are all over the world. (I'm not going to use the words "pedantic" and "Australia", in the same sentence, though).
The Delta guys, as well as United and American won't be aware of them. Although, "Charlie, Charlie" is not a term I've ever heard in the US or anywhere else, it may be more of a US military term as they tend to have more former military guys among their ranks.

Just to add to the vote as has been said it's an HF term meaning affirmative and FWIW certainly used a lot by Brits and others on the North Atlantic tracks and Africa in the days before CPDLC, so it is certainly not just an Aus thing.

I believe "brevity codes" such as Charlie and Roger are a spin-off of the equivalent telegraphy brevity codes, because of course telegraphy preceded voice radio communications.
Note: I learned and used telegraphy starting in 1962 as a teen, and was a CW/telegraphy operator in the USN, back when ships were made of wood and sailors were made of steel.
- Roger => voice = "received," but it never, ever means "affirmative" or "yes," though we have all heard this incorrectly used for that.
- R => Telegraphy = "received," but it never, ever means "affirmative" or "yes" ...
- Charlie => voice = "correct"
- C => Telegraphy = "correct"
