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.
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 don't think anyone ever intended for text rendering to be a "sufficiently powerful formal system" like second-order logic, number theory, or like Hofstadter says the human brain is. I would hope that, in the absence of bugs, rendering text X on computer system Y would be a plain old computable function.
