Corrupted JSON in message data

FYI Brian mentioned this is a known issue but posting here for awareness.

One thing I noticed is that sometimes the messages seem corrupted and can’t be parsed (invalid JSON).

[{“e”:“md”,“d”:{“quotes”:[{“id”:333776,“timestamp”:“2021-06-15T12:40:30.842Z”,“contractId”:333776,“entries”:{“Bid”:{“price”:1865.9,“size”:5},“TotalTradeVolume”:{“size”:4,“Offer”:{“price”:1866.2,“size”:2},“LowPrice”:{“price”:1860.1},“Trade”:{“price”:1864.9,“size”:1},“OpenInterest”:{“size”:978},“OpeningPrice”:{“price”:1866.4},“HighPrice”:{“price”:1867.2},“SettlementPrice”:{“price”:1864}}}]}}]

The JSON looks normal but when I paste into my editor, it looks like this:

I am not sure what these characters are but might be something to check into.
