Worked perfectly in the HN Summary channel on Telegram, which uses GPT to summarize all submissions as they're posted!

EDIT: actually I don't think this was the intended result, but something is definitely up. Fun!

Try this instead: xsel | iconv -t UTF-32 | tr -d '\000\016'

[cedws]

Unicode was a mistake.

[dcsommer]

Many parts were. Overall, though, I am glad it exists compared to the before-times.

[tambourine_man]

I did the much same thing (pbpaste | xxd), but don't understand how the hidden characters are tipping ChatGPT.

[mminer237]

Seems like some encoding difference. You can see the hidden message if you read it as UTF-8: https://www.babelstone.co.uk/Unicode/whatisit.html?utf8=Past...

[goodside]

It’s non-printing Unicode tag block characters that correspond directly to ASCII and the AI is able understand them. It’s a deprecated feature of Unicode once used to encode the language of text, but now its only supported usage is in country flag emojis.
