My new name doesn't have a middle name yet, so I'm accepting suggestions on what I could adopt that'd break as many systems as possible.

Obvious answers:
* null
* an emoji
* U+FFFD �
* half of a unicode surrogate pair
* EICAR
* some kind of prompt injection
* the entirety of DOOM, base64 encoded
* an illegal prime
* the source to decss
* 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0

@foone this one's nice too

@foone there a fun time when browser layout engines didn't handle a lot of the unicode format modifiers. I forget which code point it was exactly, but there was one you could just keep repeating and every time you did it would hoist your text vertically upwards by like 8 pixels or so. Repeat enough of them, and you could do things like make your text appear on top of other people's forum posts.

this was a fun time because you could just write DISREGARD, I SUCK on someone's post, mid-argument

Old versions of Java Swing didn't handle it well at all. I remember it looked something like a musical note when rendered by Swing. There was a multiplayer Go server with a Java client called "KGS" and you could spam that in chat and it would draw all over the whole thing, even up out of the chat pane all over the entire window UI

@foone okay hear me out. perfect middle name here

@foone it's pronounced "Sharktrumpet"

@foone

some weird stuff happens due to text layout engines trying to stop you from writing all over the page.

like this shit

normally repeating this thing would walk a ladder up all over the page, but chromium is like 'no you don't' and resets its position, which means the more times you repeat it, the bolder it gets because it's stacking

@gloriouscow @foone hahahaahaha oh NICE
@gloriouscow @foone we can't demonstrate it on fedi because no font control, but calligraphy fonts are often fascinating for how they end up drawing way, way outside their bounds
