You get all those space characters working and then some jerk comes along and uploads a file like this: ŗ̶̧̢͓̳͍͙͔̳̻̥͉̭͓̫̟͍̞̭͉͓͉̮̹͍͚̳̹̬͉͚̰͈̘̐̊̾̈̀̒͒̀͛̓̋̔͊̏͘̚ę̴̨̛̣͙̤̟̬̩̟͙͖̥̹̱̱̊͑͗̇̇͛̆̈́̃͋̓̀̔̍̍̌̐͊̎̓̅̀̕ͅģ̴̹̜̘͍̱̑͐̉̌̐̄̊͛̎́̐̌̅̈́͂͑̈́̋̔͂̊̊̒̒̔͛͆̚͘̕͠e̶̙͕̫̳̘͐̾́̑͆̓͂̿͊̊̍͛͐̌̆͗̌̅̅̔͊̂͛͗̅̕͝͝͝͝x̵̢̧̦̫͖̝̥̹͓̬͖̤̩͚̝̫̋̃̅̈́̆͋̌͑́̎̈́̊̾͒̀̒̎̓͛͊̿̓͊̀̍͐̆̚͝͝-̴̨̮̯͖͖̠̜̲̪͕̘͈͖̮̈́̓̐̃́̅̄̏́̍̉̐͌́̔̓̄͋͗̐̕͜͝ţ̴̢̧̖̗͖̞̮̫̦̼̝̺̼̱̳͓͉̜̟̤̲͖̻͙́̌̈̌̈͆̾̄͊̿̏̓͗̈́̕͜ͅh̶̢̧̨̥̭̼̟̣͖̯̗̤̖̙͉͕̙͎̰̠̝̖͈̻͙̪̮̘̯̻̼͕͓̖̣͈̽́͊̎͐͌̆̍̎̏̿͐̒́͋͑̍̿̎͆̑͆̄͂̀͐̄͑̀͗̿̽̎̾̊̕͝͝͝͝͝ͅi̴͚͈͍̫̮̝̣͖͉͓̯̠̙̭̟̖̘̾̓̄̈́̒̏̽̆̉̿͛̀́̃̋̒̈́͋̂̇̈́͛̕͜͠͠͝ͅs̶͇̖̳̞͉̱̞͓̖͔͔͍̗͇̖̮̹̅͊̔͋͊̈́̎̐̆̋̒̀̍̕͜ͅ.̴̧͎͇̰͉̼̱̰̦̟̑̋̏͌̍͊͑̄̀͌́̆̓͛̒̆̾̉͐̄̂̈́͆̒̃͗̐̂̎̈́̈͛̿́͛̾̚͘͜͝͝ͅȩ̷̡̲̪̱̪̥̳͍̼̰̘̗̹͙͙͓̣̟̩̥̥̖̠̪̮̹̞̥̻͎͖͍̯̂͑̏̑̆̍͋̎͛̅̑̑̏̎̓̀̓̒̈́͊͌̀̈́̒̌͐͂͛̊̍̐͂́̔̌̾͐̈́̋̇̏̚͜͝͝͝͠ͅx̶̧̛͚̗̜̪͍͖̘̙͎͚͇͙̬̱̟̭͓̺̙͍̖̱͚̣̘̪̭͔͔̮͎̬̪̤̹̟͔̩͍̬͕͔̩͐̈́̒̂͛̂̈̀̿̍̔̓̓̀̃̍͆̈́̍̓̌͐̈́̾̇̎̑͌͒̄̆̿̍͆̅͗͆͘͠͝͝ͅͅͅe̷̢̡̡̨̧̛͕͚̬̮̞̥̼͍͔̝̟̝̯͈̟̥͖̱̹̣̩̼̩̅̌͌̑̎̐̀̽̏́͐̋̏̎̎͛͌̀̊͊͒̑͌̎̎̑͊̌̉͆̾̚͘̚͜͠͠͠͝͝ͅͅͅ
For anyone who is curious (and acolytes of Zalgo): "In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character. So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model."

Hah, lucky for me Chrome on Ubuntu didn't implement the spec correctly. ;)
This legitimately made me laugh out loud in my office.
The characters reach up off the screen as I reply to this. They overlay the comment above you. Amazing. How?
It's usually called Zalgo text, and it's what you get when you start stacking all kinds of Unicode diacritics on poor unsuspecting characters.
https://en.wikipedia.org/wiki/Zalgo_text
This is the best generator I found: https://lingojam.com/GlitchTextGenerator
I find http://animalswithinanimals.com/generator/generator.html much more controllable.
Interestingly I get different behaviour per browser/OS. Firefox/Linux clips it to the bounding box of the parent element, Firefox/Mac and Safari/Mac clip it to the line height, and only Chrome/Mac lets it extended further.
Firefox and Safari on iOS 15 both render all the glyphs attached to the base character. Vivaldi, Chrome and Firefox on Win10 all render them stacked and overlapping the parent and child comments.
Huh, I tried it in Chrome to see how it reacted here and it maintained about the same position as it did in my usual browser, Firefox.
Until now, I haven't actually thought of what would happen if zalgotext occurred anywhere other than a web browser. Looking forward to the five minutes of fun with the file manager and whatnot.
768 characters is too long for macOS it seems. (References online say HFS+ has a limit of 255 UTF-16 characters. Didn't find anything for APFS immediately... edit: same for APFS)
Please don't Zalgo on HN. It's enough to speak its name.
It would be one thing if it was making other comments difficult to read or causing browser issues, but I appreciated the demonstration that both would presumably be possible on certain browsers
Honest question - what the heck are those characters?
It corrupted text or "Zalgo" text, it relies on diacritics.
See this answer on stackoverflow:
https://stackoverflow.com/questions/1732348/regex-match-open...
I disagree with calling it "corrupted." We're not tricking the browser into trying to render garbage bytes that are actually the middle of a jpeg or something. It's actually valid Unicode. It's an edge-case which is not seen in regular usage, but it's technically following all of the rules.

It was a great joke for a couple weeks two internets ago.
> two internets ago
It's been like three internets since I heard someone using "internet" as a measurement of time.
It's actually interesting to think about "generations" of internet, just like generations of people, and how the culture shifted between them.
There was a time in the early '00s when broadband was catching on, yet YouTube didn't exist. A time when Ebaumsworld and Newgrounds ruled the internet. When Homestar Runner was pop internet culture. Weebls Stuff. The frog blender.
In digital typography, combining characters are characters that are intended to modify other characters. The most common combining characters in the Latin script are the combining diacritical marks (including combining accents).
https://en.wikipedia.org/wiki/Combining_character
Specifically _Vietnamese_ combining characters. The Vietnamese writing system uses multiple combining characters at a time, and stacks them vertically. Throw in a few that wrap around the character like t҉his, some 𝑎lternatᵉ lꬲttꬲr fᵒrms, disturbing imagery, and perhaps a few other tricks, and you have zalgo.

Combining diacritic marks.
Glad you didn’t choose a sequence that crashes my browser.
regex this, bravo
