     i should also note that zalgo cannot be summoned on all operating systems / applications. i'm not sure of the exact requirements to make it render, but i'm sure someone smarter then me could answer.

     Ah, things get tricky here; Unicode is kind of a bear when you consider 'characters' because its codepoints aren't necessarily characters. An example would be the so-called "combining characters" which you can use for things like accents or ZALGO-text.

     But Jake could still play around with Zalgo script, a type of programmable font that packed lots of digital bytes into each letter.

     I'm not saying it isn't complicated; I'm saying that it could, and should, have been done better. Instead we get a bizarre Frankenstein's-monster of techniques where some character-glyphs are precomposed (with duplicates across multiple languages) and Zalgo-script is a thing.

     A single grapheme cluster is often one or two code points, but it can be a lot of code points in the case of something like Zalgo.

     She hid the browser — let it spawn a thousand windows in the background for all she cared, her processor could handle it — and brought up the NASC++ chat window. Sure enough, Imperium had sent her a message; a string of random characters in ‘zalgo text’. Zalgo was a form of type that exploited Unicode, the international standard for rendering language characters, adding a kaleidoscope of dozens of diacritical marks above and below every character. […] Bridge recalled a story about one zalgo message that shut down a user’s online email account by overloading it with characters; […]

Zalgo

1. (programming, humorous) A notional entity said to be "released" due to unpredictable program behaviour resulting from an API's inconsistent use of synchronous versus asynchronous operations.
   • 2013 August 30, Paul, “Re: [nodejs] Downside to not wrapping sync callbacks in nextTick()?”, in nodejs (Usenet), message-ID <53ece666-5929-41ba-843c-edc4350af00d@googlegroups.com>:

     Anyway. My personal opinion is that people are making a bigger deal about it than it needs to be. Just be aware that there could maybe potentially be an issue in your app if you release Zalgo, but don't spend the hours going through and wrapping everything in nextTick just to say you are Zalgo-free even if Zalgo being released has ever doomed you.

     This works wonderfully, until you hit an exception in one of your zalgo-promise functions.

     Another crucial detail is to consider the unleashing Zalgo anti-pattern (we have seen it in action in Chapter 1, Node.js Design Fundamentals).

   • 2015 July, Daniel Parker, “Chapter 1: Asynchronous JavaScript”, in JavaScript with Promises: Managing Asynchronous Code, O'Reilly Media, →ISBN, page 6:

     The explosion in execution branches makes explaining and testing this approach difficult, and reliable behavior in a production environment more challenging. Isaac Schlueter has written a popular blog post about this titled “Designing APIs for Asynchrony,” in which he refers to the inconsistent behavior as “releasing Zalgo.”

   • 2015, Robert Fischer, “Chapter 2: Understanding Lambdas in Java 8”, in Java Closures and Lambda, →ISBN, Don’t Release Zalgo, page 29:

     The JavaScript community, for instance, has discovered a monstrous entity named “Zalgo.” […] When you are passing around lambdas, it is easy to release Zalgo if you mix synchronous and asynchronous styles.
