benswerd•1mo ago
Figured this out a couple weeks ago, hoping it can lead to some cool new art.
mkl•1mo ago
Images of what it's supposed to look like would really help, as I'm pretty sure none of my browsers are rendering it as you hoped. For me in Chrome the first image looks vaguely like a landscape, with no identifiable features, and in Firefox it looks like grass (both on Android). The dog and tree shapes look distorted and glitchy, but recognisable if you know what they're supposed to be.

I spotted a typo: "font's like".

benswerd•1mo ago
Just pushed fix to typo — can you let me know which chromium browser on which platform?

I'm primarily testing on Vivaldi on MacOS but also confirmed working on Chrome on MacOS.

gus_massa•1mo ago
I agree, a few screenshots would be helphful for users of unsuported browsers.
5-0•1mo ago
Neat! Sparklines could also benefit.
chrisfrantz•1mo ago
Love that this exists now, thank you and nice read.

FWIW, didn't have any luck with the generator at the bottom, could be user error.

benswerd•1mo ago
What browser was it in?
chrisfrantz•1mo ago
Chrome, latest stable
benswerd•1mo ago
MacOS Linux Windows or other?
bawolff•1mo ago
I can't tell if the results are just very bad or my browser is just not rendering properly. I feel like its probably the later but it would be cool to have a reference picture to be sure.
benswerd•1mo ago
which browser are you using?
gabcoh•1mo ago
I’m also not seeing the purported images on iOS 26.1 safari
frizlab•1mo ago
It apparently only works correctly on chromium-based browsers.
kibwen•1mo ago
Appears to mostly work in Firefox, including in the browser tab title, which is funny.
frizlab•1mo ago
It did not work at all for me on latest Firefox (macOS).
ilaksh•1mo ago
I am on Chrome on Android and it does not work. Although some of them it's like halfway there.
marginalia_nu•1mo ago
Does not work for me with Chrome, though I guess it's missing some font.
benswerd•1mo ago
It does not work on iOS Safari at all, it should show a warning at the top saying so
doodpants•1mo ago
I do not miss the days of "This site best viewed with browser X".
egypturnash•1mo ago
Nor on MacOS Safari.
bawolff•1mo ago
Android chrome and firefox.
esperent•1mo ago
Same here, Brave on Android. I see a load of wavy vertical lines with some striations that could pass for abstract art, but no obvious image.
krackers•1mo ago
Seems like a more advanced version of zalgotext (which also uses combining marks)
benswerd•1mo ago
This is beautiful and I did not know it existed until now tx

Edit: Apparently, you cannot write direct html entities.

Edit: And you cannot directly write the characters either. Rendering seems rather finicky on Firefox, while Chrome seems somewhat consistent.

Actually, on Chrome, copying the characters directly "kind of" worked. They're still shown next to each other, yet some of them combined and actually created towers.

Writing the HTML entities on a private webpage and then copying them over seemed to work the best.

Edit: Apparently, at least some of the Devanagari unicode behaves similarly.

Edit: Several other languages combining marks taken from https://www.cogsci.ed.ac.uk/~richard/unicode-sample-3-2.html and https://www.compart.com/en/unicode/category/Mn seem to also work.

After further testing, Both browsers are really finicky, and have wildly different interpretations of pasting combining characters directly, vs writing HTML entities, vs copying the combined stack from an existing site.

senfiaj•1mo ago
When I visit such pages, my impression is that someone want to break my browser.
benswerd•1mo ago
thats the vibe i was going for
ilaksh•1mo ago
Another thing in the category of abusing font capabilities is Harfbuzz (OpenType engine) WASM, which if compiled into an application allows fonts to basically run any code. A few examples are an LLM or a Tetris font. Apparently this WASM support is in the font rendering for Chrome and Firefox supposedly.

I was really tempted to try to use it to make a Harfbuzz OS.
