aaronpk So it's not that it's "invalid", it's that there is no mechanism for clients and servers to communicate that the text is markdown so it's up to the server to handle it how it wants. The nice thing is that it's your server so you can choose to make that work if you want. And chances are you're the only person sending data to your server so again it works out fine in practice.
