i do most of my algebraic formulas with the compose key and a custom compose map mostly written by mark shoulson https://github.com/kragen/xcompose
for the above, after a false start picking random unicode characters, i realized that maybe i shouldn't use a modern language because someone who actually uses the language might feel like i was calling them an extraterrestrial, so i switched to googling archaic scripts. i pasted part of the old permic table from wikipedia
>>> s = '''๐โ ๐โ ๐โ ๐โ ๐โ ๐โ ๐โ ๐โ ๐โ ๐โ ๐โ ๐โ ๐โ ๐โ ๐โ ๐โ

>>> print(''.join(c for c in s if ord(c) >= 0x10350))

it's funny how this conversation has swung from the extreme of universal constants of the universe to the opposite extreme of completely arbitrary and historically contingent things like which ideograms (themselves completely arbitrary) are prevented from being posted by implementation bugs in hacker news
Thanks so much for this, let's see if copy paste works on this unix derived os. ๐๐๐๐ ๐ก๐ข๐ฃ๐ค๐ฅ
I must admit that, unlike a lot of HN'ers, I'm using a virtual keyboard on a heldheld device to type comments; I never took the effort of looking up how it is done though it must have to do with extended char sets.
