That was my question and it's still not answered well here. I guess people post the colors that led up to their solution but no the actual letters.

Might be good to add it to the original post for clarification. I play Wordle but didn't quite get what they were using for source data.

It wasn't obvious to me when I first started playing Wordle, but you can actually share an emoji-fied version of your game (without the letters) by clicking "Share" when the statistics window pops up. I didn't think to do that at first, but when I noticed everyone on social media posting their Wordles with the exact same format, I figured it had to be buried in the game somewhere.

It's the text you copy/paste to share your Wordle results on social media.

Huh, I thought HN stripped out emojis from posts. Has that changed, or is there a limited subset that are available?

The black and white squares are in the older Unicode "Miscellaneous Symbols and Arrrows" block so I guess they're allowed. Several things like that are sort of "retroactively" emoji... there's a "display as emoji" or "display as text" character you can put after them.

What HN does and doesn't allow seems somewhat arbitrary, things like the star emoji are in that same block and yet are not allowed as far as I can tell.

Maybe because ■ is part if ASCII?

Edit: ⬛⬜ work, the colored ones don't.

⬛ and ■ are different characters. But it looks like HN still strips most emoji.

It is definitely not part of ASCII.
