Text formatting in things like nbts for mobs and items such as names is broken. Instead of "Name" I have to type in "{\"text\":\"Name\"}"

The version number that appears below a world name has strange text. When making an nbt for an item I would have to do {display:{Name:"{\"text\":\"Name\"}"}} instead of {display:{Name:"Name"}}, and an entity would have to have {CustomName:"{\"text\":\"Name\"}"} instead of what it is normally as well. I am unable to detect names with [name=""] with or without quotation marks, and have to use nbt.

If you create an item using "" instead of {\"text\":\"\"} it will crash the game, and the only way to be able to enter the world again is by deleting or editing player data.

I am unable to find others reporting this as a bug or find confirmation that this is part of the snapshots, but I am assuming this is a bug due to dinnerbone's tweet saying that the display of the version was a bug.
