Send an empty tweet

Twitter doesn't allow its users to post empty tweets, or tweets that only contain regular space characters.

To post an empty tweet, you can just use the invisible U+3164 HANGUL FILLER character! Click the "Copy" button below which copies the character into your clipboard, then paste into Twitter's tweet editor, and hit the "Send" button. Done!

This works both in Twitter's smartphone app and in the web client.
