What it checks

countGraphemes(text) <= 280, with URLs counted as 23 characters regardless of their real length (t.co wraps every URL).

​
Why 280 + 23

Twitter’s tweet.create enforces 280 graphemes. URLs are wrapped by t.co to a fixed 23-character length, so a 100-character URL still counts as 23. We subtract the real URL length and add 23 for each URL.

​
Remediation

Trim the tweet, or break it into a thread.
