Extended Tweet - Entities vs ExtendedTweet.Entities



I would like to have a confirmation that if an entity is available in tweet.entities and tweet.extended_tweet.entities, they will both contain the exact same information? specially regarding the indices.

Same for tweet.extended_entities and tweet.extended_tweet.extended_entities.

I want to make sure how the indices will work in such cases.

Also please note that I read :

The existing entity fields (mentions, urls, media, etc.), will only contain entities that are fully contained within the text value. The from and to indices within each entity must be a valid code point index within the text value. The truncation point will avoid truncating mid-entity. A URL entity for the appended self-permalink will be appended to the list of entities.

But I am still not sure how they will behave.
