Unhelpful error message when toot over character limit

[collingsr]

Content warnings are included in the character limit for toots, but the app only counts the number of characters in the body of the toot. Then, when you attempt to send the toot you get a vague error "Failed to toot" with no info as to why the toot failed. You can see in the screenshot how it shows 27 characters left, but also the error message.

It would be helpful if the software could count content warning text as part of the total character count and change the error message to say the toot is over character count.
