Anyone got any information on how the text rendering bug actually works (not just hand-waving it away as "oh it's UTF-8")?

I can see that the file alternates between segments of:

- Repetitions of the glyph "t̴́̍̒", which is a lowercase t with a combining tilde overlay, an acute accent, a vertical line above, and a turned comma above

- Random-looking ASCII characters with lots of apostrophes (spelled as ' in the HTML)

- Short sequences of spaces, non-breaking spaces, and zero-width joiners

- Occasional emoji

The "t̴́̍̒"s manage to slow down my terminal and glitch its rendering a bit. Is it that they're unexpectedly tall? But we've had zalgo-text for a while and it hasn't actually crashed devices.

I find it unexpectedly hilarious that we now have issues that cannot be fully described without running the risk of crashing our machines. Its as if there are certain unholy words that could cause us to faint if we were to utter them.

Sounds right out of Gödel, Escher, Bach :

Achilles: I see the dilemma now. If any record player—say Record Player X—is sufficiently high-fidelity, then when it attempts to play the song "I Cannot Be Played on Record Player X", it will create just those vibrations which cause it to break...So it fails to be Perfect. And yet, the only way to get around that trickery, namely for Record Player X to be of lower fidelity, even more directly ensures that it is not Perfect. It seems that every record player is vulnerable to one or the other of those frailties, and hence all record players are defective. (p77)

I'm also thinking Snow Crash.
